The broad spectrum of heterozygous versus homozygous JAK2V617F mutated MPN consists ET, ET with early features of PV (prodromal PV), classical PV, masked PV, advanced PV and post-PV myelofibrosis. Combined use of bone marrow histology and increased erythrocyte counts above 5.8x1012/L can replace increased red cell mass at time of presentation as the pathognomonic clue for the correct diagnosis of hetero/homozygous or homozygous mutated PV. Erythrocyte counts are in the normal range below 5.8x1012/L in heterozygous JAK2V617F mutated ET and prodromal PV but above 5.8x1012/L in heterozygous-homozygous or homozygous mutated PV. The bone marrow cellularity and morphology in pre-fibrotic ET, prodromal PV and PV carrying the JAK2V617F mutation are overlapping showing clustered increase of large mature pleomorphic megakaryocytes (M) with no increase of cellularity (<60%) in ET. The bone marrow is hypercellular (60%-80%) due to increased erythropoiesis megakaryopoiesis (EM) in prodromal and classical PV and trilinear hypercellular (80%-100% due increased megakaryopoiesis, erythropoiesis and granulopoiesis (EMG) in advanced PV and masked PV. Bone marrow cellularity ranging from normal (<60%) in ET to increased erythropoiesis (EM) in prodromal PV to hypercellular (80-100%) in advanced PV and masked PV largely depends on increasing JAK2V617F mutation load from low to high on top of other biological MPN variables like constitutional symptoms during long-term follow-up. MPL515 mutated ET is featured by an increase of clustered small and giant megakaryocytes with hyper-lobulated staghorn-like nuclei in a normal cellular bone marrow. The third entity of pronounced JAK2/MPL wild type ET associated with primary megakaryocytic granulocytic myeloproliferation (PMGM) without PV features proved to be caused by calreticulin (CALR) mutation. CALR mutated thrombocythemia is characterized by dual proliferation of megakaryocytic and granulocytic bone marrow proliferation of dense clustered large to giant immature dysmorphic megakaryocytes with bulky (bulbous) hyperchromatic nuclei, which are not seen in MPL515-mutated Thrombocythemia and JAK2V617F-Thrombocythemia, prodromal PV and classical PV.
Primary myelofibrosis is not primary anymore since the discovery of MPL515 and CALR mutations as driver causes of mono-linear megakaryocytic and dual megakaryocytic granulocytic myeloproliferation and secondary myelofibrosis

Primary myelofibrosis (PMF) is a distinct clinicopathological myeloproliferatve disease (MPD) not preceded by any other MPD ET, PV, CML,... Combined use of bone marrow histology and increased erythrocyte counts above 5.8x1012/L can replace increased red cell mass at time of presentation as the pathognomonic clue for the correct diagnosis of hetero/homozygous or homozygous mutated PV. Erythrocyte counts are in the normal range below 5.8x1012/L in heterozygous JAK2V617F mutated ET and prodromal PV but above 5.8x1012/L in heterozygous-homozygous or homozygous mutated PV.

The PVSG/WHO versus the Rotterdam European clinical, molecular and pathological diagnostic criteria for the classification of myeloproliferative disorders and myeloproliferative neoplasms (MPD/MPN): From Dameshek to Georgii, Vainchenker and Michiels 1950-2018
Published on: 17th April, 2019
OCLC Number/Unique Identifier: 8164019922
The present article extends the PVSG-WHO criteria into a simplified set of Rotterdam and European Clinical, Molecular and Pathological (RCP/ECMP) criteria to diagnose and classify the myeloproliferative neoplasms (MPNs). The crude WHO criteria still miss the masked and early stages of ET and PV. Bone marrow histology has a near to 100% sensitivity and specificity to distinguish thrombocythemia in BCR/ABL positive CML and ET, and the myelodysplastic syndromes in RARS-T and 5q-minus syndrome from BCR/ABL negative thrombocythemias in myeloproliferative disorders (MPD). The presence of JAK2V617F mutation with increased erythrocytes above 6x1012/L and hematocrit (>0.51 males and >0.48 females) is diagnostic for PV obviating the need of red cell mass measurement. About half of WHO defined ET and PMF and 95% of PV patients are JAK2V617F positive. The combination of molecular marker screening JAK2V617F, JAK2 exon 12, MPL515 and CALR mutations and bone marrow pathology is 100% sensitive and specific for the diagnosis of latent, early and classical ECMP defined MPNs. The translation of WHO defined ET, PV and PMF into ECMP criteria have include the platelet count above 350 x109/l, mutation screening and bone marrow histology as inclusion criteria for thrombocythemia in various MPNs. According to ECMP criteria, ET comprises three distinct phenotypes of true ET, ET with features of early (“forme fruste” PV), and ET with a hypercellular erythrocythemic, megakaryocytic granulocytic myeloproliferation (EMGM or masked PV). The ECMP criteria clearly differentiate early erythrocythemic, prodromal and classical PV from congenital polycythemia and idiopathic or secondary erythrocytosis. The burden of JAK2V617F mutation in heterozygous ET and in homozygous PV is of major clinical and prognostic significance. JAK2 wild type MPL515 mutated normocellular ET and MF lack PV features in blood and bone marrow. JAK2/MPL wild type hypercellular ET associated with primary megakaryocytic granulocytic myeloproliferation (PMGM) is the third distinct CALR mutated MPN. The translation of WHO into ECMP criteria for the classification of MPNs have a major impact on prognosis assessment and best choice for first line non-leukemogenic approach to postpone potential leukemogenic myelopsuppressive agents as long as possible in ET, PV and PMGM patients.
Neurobiology of Common Sleep Disorders

Sleep disorders in human are common and detrimental to general health of all age groups. While the neurobiological mechanisms of sleep disorders are not yet fully understood, recent advances in research on the sleep-wake regulation mechanism, genetic and epigenetic factors, cognitive, emotional and physiological changes related to sleep have shed light on the mechanistic basis of sleep disorders. Over the past two decades, studies in Drosophila have yielded new insights into basic questions regarding sleep function and regulation. More recently, powerful genetic approaches in the fly have been applied toward studying primary human sleep disorders and other disorders associated with dysregulated sleep. In this review, we discussed recent advances in neurobiology of sleep-wave cycle and common sleep disorders. Understanding these mechanisms are important in the diagnosis, treatment and prevention of these common disorders.
Mimicking multiple sclerosis - Ghost tumor that comes and goes in different parts of the brain without any treatment
Published on: 9th July, 2019
Lesions that spontaneously come and go in central nervous system without any treatment at different time points and at different locations (CNS) usually lead ones to think of the possibilities of multiple sclerosis. However, sometimes there are exceptions. Surgical biopsy remains an important tool for definitive diagnosis in difficult cases. We report a case of intracranial diffuse large B cell lymphoma that spontaneously disappeared without any treatment and then reappeared at different time points and different locations.
Gastrointestinal stromal tumor resulting in recurrent colic in a arabian horse gelding a report of case
Published on: 2nd November, 2020
OCLC Number/Unique Identifier: 8697203989
Background: A Grey 12-year-old Arabian endurance horse gelding was referred to the SHS Veterinary Center for anorexia, mild colic of 5 days duration, and melena of 1 day duration. The owner reported recurring colic, 12 episodes of mild colic in the previous year.
Methods: On admission, vital signs were within normal limits and body condition score was estimated to be 3/9.
Results: Packed cell volume (PCV) was 28% [reference range (RR): 31% to 47%] and plasma total protein was 58 g/L (RR: 60 to 80 g/L). Hematochezia was observed. Abdominal ultrasound examination detected no abnormalities. Over the next 12 h, the horse experienced hematochezia and several mild episodes of colic and death. A necropsy was performed. A mass arising from the right dorsal ascending colon near the base of the cecum and extending transmurally from the colonic mucosa into the mesocolon was a 8 cm × 5 cm × 8 cm firm, homogenous, tan mass. The portion of the mass that extended into the colonic lumen was pedunculated, with an ulcerated surface. The adjacent segments of colon were markedly reddened and edematous. Histologically, the mass was comprised of large interweaving sheets of small, spindle cells with ill-defined cell borders embedded in abundant myxomatous matrix. Tumor cells contained scant eosinophilic cytoplasm and oval to elongate nuclei with finely stippled chromatin and inconspicuous nucleoli. Mitotic figures were rare (1/10) high power fields. Tumor infiltrated between the muscularis interna and the muscularis externa at the myenteric plexi.
Conclusion: Gross and histologic appearance, were consistent with a diagnosis of gastrointestinal stromal tumor.
Obesity may increase the prevalence of Parkinson’s Disease (PD) while PD may reduce obesity index in patients
Published on: 6th April, 2020
OCLC Number/Unique Identifier: 8589557020
Objective: Currently, Parkinson’s disease (PD) is becoming more common among younger people of ages from 30 – 40 years. The incidence is higher among patients with higher body mass index (BMI), and some reports had it that Obesity is a risk factor for PD while some reported that there is no relationship between obesity and PD. PD patient at the time of diagnosis has an above-normal BMI but which goes below normal as the disease progresses. Therefore, it is essential to explore the relationship between PD and Obesity.
Methods: 349 outpatients and inpatients with PD were selected from Jiangsu University Affiliated People’s Hospital from January 2014 to December 2018, while 74 inpatients with non-cerebrovascular illness in the same period were selected as the control group. According to Hoehn-Yahr grade, Parkinson’s patients were divided into three groups. The height, weight, waist and hip circumference, total cholesterol (TC), Total Glycerol (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured and recorded. The relationship between the severity of Parkinson’s disease and blood lipids was evaluated.
Results: The BMI of patients with PD in the early stage was higher than that of the control group, but lower than that of the control group in the late stage, and the level of blood lipid in the patients with early PD was significantly higher than that in the control group and patients with advanced PD, especially in TG. The waist circumference and hip circumference of the patients with early PD were higher than those in the control group, but there was no statistical difference.
Conclusion: i) Obesity may increase the prevalence of PD. ii) The BMI of patients with PD shows two-way changes in different periods. iii) The BMI is higher and cholesterol is more elevated in the early stage of patients with PD, while at the advanced stage of the disease, the BMI and lipid levels of the patients showed a downward trend, which may be associated with a metabolic syndrome associated with dopamine depletion.
Atlantoaxial subluxation in the pediatric patient: Case series and literature review
Published on: 26th November, 2020
OCLC Number/Unique Identifier: 8799428362
Objective: Atlantoaxial subluxation (AAS) occurs when there is misalignment of the atlantoaxial joint. Several etiologies confer increased risk of AAS in children, including neck trauma, inflammation, infection, or inherent ligamentous laxity of the cervical spine.
Methods: A single-center, retrospective case review was performed. Thirty-four patients with an ICD-10 diagnosis of S13.1 were identified. Demographics and clinical data were reviewed for etiology, imaging techniques, treatment, and clinical outcome.
Results: Out of thirty-four patients, twenty-two suffered cervical spine trauma, seven presented with Grisel’s Syndrome, four presented with ligamentous laxity, and one had an unrecognizable etiology. Most diagnoses of cervical spine subluxation and/or instability were detected on computerized tomography (CT), while radiography and magnetic resonance imaging (MRI) were largely performed for follow-up monitoring. Six patients underwent cervical spine fusion, five had halo traction, twelve wore a hard and/or soft collar without having surgery or halo traction, and eight were referred to physical therapy without other interventions.
Conclusion: Pediatric patients with atlantoaxial subluxation may benefit from limited 3D CT scans of the upper cervical spine for accurate diagnosis. Conservative treatment with hard cervical collar and immobilization after reduction may be attempted, but halo traction and halo vest immobilization may be necessary. If non-operative treatment fails, cervical spine internal reduction and fixation may be necessary to maintain normal C1-C2 alignment.
Granulomatosis with polyangiitis (GPA) in a 76-year old woman presenting with pulmonary nodule and accelerating acute kidney injury
Published on: 20th January, 2020
OCLC Number/Unique Identifier: 8516756417
Granulomatosis with polyangiitis (GPA), a form of ANCA-associated vasculitis (AAV), is a rare disease with an often-occult presentation. It is more common in 4th and 5th decades of life but can be seen in all ages.
This case report details a 76-year-old female presenting with abdominal pain, generalized weakness, and malaise, who was found to have pulmonary nodules on chest imaging. Biopsy of the lung nodule showed organizing pneumonia. Initially, antibiotics were used to treat the patient. However, she developed acute renal failure a few days after presentation and found to have positive serum C-ANCA as well as elevated ANCA-PR3 serologies. A subsequent kidney biopsy demonstrated pauci-immune necrotizing and crescentic glomerulonephritis that was consistent with GPA and the patient was started immediately on combination immunosuppressive therapy, plasmapheresis, and hemodialysis.
GPA’s clinical and radiological presentation can mimic other common conditions such as pneumonia, malignancy, bacterial sinusitis, pulmonary tuberculosis, sarcoidosis, and urinary tract infection. Because of this, a high level of suspicion is required for early diagnosis and treatment to alter the high mortality rate in this disease entity. All forms of ANCA-associated vasculitis (AAV) should be in the differential diagnosis for all patients presenting with multiorgan system involvement particularly in individuals with pulmonary and renal manifesations.
A remote cause of anuria in a child
Published on: 26th February, 2020
OCLC Number/Unique Identifier: 8582359236
Acute renal injury is a rare complication of idiopathic nephrotic syndrome with mesPGN. Here we present a 2-year-old male patient with 4 days history of anuria, generalized edema and hypervolemia. Any evidence other than proteinuria and renal failure could not be identified with laboratory tests and doppler ultrasonography. Anuric presentation was thought to be related with rapidly progressive glomerulonephritis, diffuse mesangial sclerosis or acute tubular necrosis. However, renal biopsy revealed mesangial proliferative glomerulonephritis (mesPGN). Prednisolone 2 mg/kg/day was prescribed. Diuresis was started gradually and on the 10th day of disease, anuria was resolved and acute renal injury recovered without any sequel. This case is presented because of the incompatibility between clinical findings and histopathologic diagnosis. It is concluded that although rare, anuria and acute renal injury could be the presenting symptom of idiopathic nephrotic syndrome in childhood.
Is beta 2 urinary microglobulin a biomarker of topographical discrimination between high and low urinary tract infection?
Published on: 28th April, 2020
OCLC Number/Unique Identifier: 8588737014
Urinary tract infections are common affection in the general population.
Diagnosis is often easy in the presence of evocative clinical signs.
The diagnosis of urinary tract infection is evoked in the presence of an uropathogenic germ in the urine in sufficient quantity associated with urinary signs. The presence of lower back pain, chills, fever higher than 39° is suggestive of a high urinary tract infection localized in the kidney, the absence of fever associated with dysuria is suggestive of low urinary tract infection localized in the bladder.
Specific meningoencephalitis in patients with transplanted kidney
Published on: 17th June, 2020
OCLC Number/Unique Identifier: 8628628844
We described a case of specific (tuberculous) encephalitis in a patient after kidney transplantation. Immunosuppressive therapy, continuously required in post-tranplant period, may cause various complications, such as infections. Specific meningoencephalitis is an infection that is rarely diagnosed and more common in immunocompromised patients.
Case report: A 30-year-old man had kidney transplantation (kidney donor was his father). He previously was two years on chronic hemodialysis treatment because of end-stagerenal disease based on diabetic nephropathy. He has diabetes type 1. The early post-transplant period duly passed with satisfactory clinical and laboratory parameters of renal function. Two months after transplantation, he presented with febrile condition, signs of septicemia and dehydration with significant neurological deficit and expressed meningeal signs. In cerebrospinal fluid we found lymphocytosis, elevated proteins and positive micobacterium tuberculosis antibodies (Hexagon method) and we suspected to specific etiology of meningitis. Performed computed tomography (CT) scan of the brain with contrast confirmed the expected finding.
Due to the poor prognosis of infections of the central nervous system (CNS) in immunocompromised patients, only prompt diagnosis can improve survival in this group of patients. The therapeutic protocol after kidney transplantation include the prophylactic use of antituberculous drug (Isoniazid 300 mg) during the 9 months.
Biomarkers in acute kidney injury
Published on: 20th July, 2020
OCLC Number/Unique Identifier: 8635214937
Acute kidney injury is a common condition associated with high morbidity and short-term mortality. Its pathophysiology varies according to the numerous conditions associated with its genesis. Biomarkers allow detecting changes at the level of kidney function; therefore, they play an important role in the prevention, early diagnosis, therapeutic response and prognosis of acute kidney injury. The search for biomarkers for acute kidney injury began over 15 years ago; initially, only serum creatinine was available for diagnosis. However, throughout history, great advances have been made in research, which have allowed the finding of new biomarkers in order to improve the health and quality of life of patients. A narrative review of the literature is carried out on the basis of available scientific evidence to clarify the role and importance of biomarkers in the context of acute renal injury.
Frequency of renal tubular acidosis in children with down syndrome
Published on: 2nd October, 2020
OCLC Number/Unique Identifier: 8691889815
Background: Down syndrome (DS) is associated with various congenital diseases and malformations, including those of the kidneys and urinary tract. It has been thought that renal tubular acidosis (RTA) is more frequent in this population. The objective of this study was to assess the frequency of RTA and, secondarily, of other renal and urological disorders in persons with DS.
Method: An observational, ambispective, descriptive and cross-sectional study of patients diagnosed with RTA, or suspected kidney or urological disorders, was carried out from July 2016 to September 2017 at the Down syndrome clinic of the Mexican National Institute of Paediatrics. Urinalysis was performed, along with analyses of venous blood gas, sodium, potassium, chlorine, calcium, phosphorus, albumin and creatinine. Those with any abnormal values were referred to nephrology for diagnostic evaluation.
Results: Of a total of 700 patients seen at the clinic, 47 met the selection criteria. Of these, 32 had no RTA or other renal or urological alterations. The remaining 15 continued to the second phase of the study, where 6 were diagnosed with nephropathy or uropathy (RTA, systemic arterial hypertension, monosymptomatic familial haematuria, mild renal failure secondary to reflux nephropathy, urinary tract infection or right ureteropelvic stenosis). Four had mild metabolic acidosis without meeting the criteria for diagnosis of RTA.
Conclusion: RTA is not more common in children with Down syndrome. Nephropathies and uropathies should be investigated in the evaluation of DS patients.
Diffuse alveolar hemorrhage: Unusual presentation of systemic lupus erythematosus
Published on: 22nd April, 2021
OCLC Number/Unique Identifier: 9026719858
Diffuse alveolar hemorrhage (DAH) is a rare complication of systemic lupus erythematosus (SLE) and carries a high mortality.
It was first described by Osler in 1904 as the most devastating pulmonary complication of SLE.
We describe a case of a 23-year-old girl recently diagnosed with SLE associated by a class III nephritis treated with oral corticoids and mycophenolate mofetil who developed a Diffuse Alveolar Hemorrhage DAH a few days later. The early diagnosis and the aggressive therapy allowed us to have a favorable outcome.
Prognostic factors for chronic kidney disease and end-stage renal disease in patients with lupus nephritis: A retrospective cohort study
Published on: 27th April, 2021
OCLC Number/Unique Identifier: 9022387289
Background: Lupus Nephritis (LN) occurs in approximately half of all patients with Systemic Lupus Erythematosus (SLE) and it is the most common cause of morbidity and mortality in patients with SLE. Factors associated with poor renal outcome vary among studies, and researches coming from Brazil are scarce.
Objectives: To identify the prognostic factors associated to the development of Chronic Kidney Disease (CKD) and End Stage Renal Disease (ESRD) in LN patients followed in a tertiary hospital.
Design and Settings: We conducted a retrospective cohort study set in a tertiary hospital in Fortaleza, Ceará, Brazil. Methods: We compiled a total of 214 LN patients diagnosed between 1983 and 2015. Data was collected from medical records and further analyzed using logistic regression.
Results: LN prevalence was 53.9%. The cohort had a mean follow-up of 11.2 years (SD ± 7.2 years). At the end of follow-up, 93 of 197 patients (47.2%) had CKD, and 49 of 191 (25.6%) were on regular dialysis. The main factors associated for developing CKD after logistic regression analysis were the following predictors: hypertension (HR 2.80; 95% CI 1.30-6.01; p = 0.008), time between diagnosis of SLE and diagnosis of LN (HR 0.98; 95% CI 0.97-0.99; p = 0.009) and discontinuation of medications (HR 2.41; 95% CI 1.08-5.37; p = 0.03).
Conclusion: Hypertension, discontinuation of medications, and time between diagnosis of SLE and diagnosis of LN are independent variables associated with the development of CKD and ESDR in our study.
Practice patterns and outcomes of repository corticotropin injection (Acthar® Gel) use in childhood nephrotic syndrome: A study of the North American Pediatric Renal Trials and collaborative studies and the Pediatric Nephrology Research Consortium
Published on: 23rd July, 2021
OCLC Number/Unique Identifier: 9140608009
Objective: We set up a U.S. registry to examine prescription patterns and patient outcomes of repository corticotropin injection (Acthar® Gel) for childhood nephrotic syndrome.
Methods: 18 participating U.S. pediatric centers performed retrospective review and prospective observation of patients < 21 years old with nephrotic syndrome treated with Acthar Gel. We captured baseline characteristics, drug regimen and duration, and disease response following treatment.
Results: 46 patients, enrolled from 2015 to 2020 were included. 27 (58.7%) were male. 18 patients (39.1%) had a diagnosis of minimal change followed by focal segmental glomerulosclerosis in 16 patients (34.7%). Median age at start of treatment was 12.5 years (IQR 8.5-17.4) compared to 5.3 years at diagnosis (IQR 2.7-10.5 years). 52% were resistant to corticosteroids. The most common Acthar Gel regimen was 80IU twice a week with a median duration of 199 days (IQR 88-365). Among 37 patients with active disease, 18 (49%) were able to achieve partial or complete remission, though all patients that had a positive response were on other immunosuppressants concomitantly.
Conclusion: We report the findings of the largest registry cohort of pediatric patients in the U.S. treated with Acthar Gel for clinically challenging cases of nephrotic syndrome. Acthar Gel was successful in inducing remission in approximately half of the patients with active disease at time of treatment. No predictors of response with respect to demographic data, age at start of Acthar Gel therapy, etiology of nephrotic syndrome, presence or absence of comorbidities, or steroid responsiveness was noted.

Cerebral arterial air embolism with anterior spinal cord syndrome after CT-guided hook-wire localization of Lung mass and pulmonary nodule
Published on: 19th March, 2021
OCLC Number/Unique Identifier: 8973613870
Systemic arterial air embolism (SAAE) is a rare but serious complication of CT-guided hook wire localization of pulmonary nodule usually with catastrophic and poor outcome. Hook wire needle localization is done pre-operatively by placing wire around or into the pulmonary nodule to provide the thoracic surgeon accurate location guidance of the target nodule for Video-Assisted Thoracoscopic Surgery (VATS) wedge resection with safety margins. Physicians should be aware of this possible complication during the procedure in order to rescue the patient promptly as it requires rapid diagnosis and management. We describe a 55-year-old male who underwent a CT-guided hook wire needle localization of left upper lobe lung cancer and left lower lobe pulmonary nodule prior to planned VATS wedge resection who developed altered mental status and bilateral lower extremities paralysis after wire placement was completed. His CT head demonstrated small air embolism in the left occipital area, confirming the diagnosis of cerebral air embolism and follow up CT and MRI of the head revealed multiple areas of brain infarction. In addition, he was diagnosed with anterior spinal cord syndrome (ACS), most likely due to anterior spinal artery ischemia from micro air embolism on the basis of clinical findings but with negative ischemic changes on MRI of the spinal cord. His mental status recovered but he remained paraplegic and transferred to inpatient rehabilitation service.
Characterization of the immune response in neuroimmune disorders in children
Published on: 20th April, 2021
OCLC Number/Unique Identifier: 9026721284
Background: A misguided auto-reactive injury is responsible for several types of central nervous system (CNS) conditions in pediatrics. We propose that, in some of these conditions, the adaptive immune system has a common cellular immune pathogenesis, driven predominantly by T cells, despite variability on the phenotypical clinical presentation.
Methods: We have characterized the CD4+/CD8+ adaptive immune response (AIR) on pediatric patients presenting with clinical symptoms compatible with Neuroimmune Disorders (NID). Flow cytometry with deep immunophenotyping of T cells was performed on peripheral blood obtained during the acute clinical phase and compared to an age-matched cohort group (Co).
Results: We found that pediatric patients with confirmed NID, exhibit a pattern of dysregulation of CD4+ lineages associated with autoimmune processes.
Discussion: The autoimmune associated CD4+ dysregulation was associated with patients with NID, as compared to healthy controls and patients with non-autoimmune diagnoses. If we can improve our capacity for early accurate diagnosis and meaningful disease monitoring of pathogenic T cell subsets, we can both expedite disease detection and may serve as a guide to the administration of effective immunotherapeutic agents.

Within one week I already received the response from the editor. All processing steps were really fast so in terms of a speedy publication I can particularly recommend the journal Archives of Biotechnology and Biomedicine. The responsible contact person of the journal was always available, which gives a trustworthy impression to the author. Also the peer review process was clear and constructive. So from my experience with Heighten Science Publications Corporation I can recommend publishing there.

Publishing an article is a long process, but working with your publication department made things go smoothly, even though the process took exactly 5 months from the time of submitting the article till the time I have favourable response, the missing part is the peer review details, which is essential in self auditing and future improvement, overall experience was excellent giving your understanding of the situation of lack of financial institution support.

Great, We are too comfortable with the process including the peer review process and quality. But, the journal should be indexed in different databases such scopus.
