The coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged in Wuhan, China and spread around the world (WHO, 2020). The genome of the SARS-CoV-2 has been reported over 80% identical to the previous human coronavirus (SARS-like bat CoV) [1]. As of May 2020, more than 5 million people have been affected worldwide with deaths amounting to 333000, the numbers increasing at an alarming rate day by day.

A respiratory outbreak of COVID-19 started from Wuhan, China and on 30 January 2020, WHO declared this infection to be epidemic, implementing public health emergency worldwide. On 11th March 2020, observing its prevalence in the whole world and WHO declared as a pandemic. Many countries completely collapse in the grip of this pandemic, as there are no effective treatments available, the precaution is the sole remedy to minimize this infection. The emergence and pandemic of SARS-CoV-2 (since the SARS-CoV in 2002 and MERS-CoV in 2012] manifest the third time outline of highly contagious and pathogenic infection with infect-ability to spread globally in the twentieth-first century. The SARS CoV-2 genome is highly identical to bat coronavirus which is considered to be the perfect natural host. This coronavirus even utilizes the same ACE2 receptor as SARS-CoV and mainly spread the infection to the respiratory tract, which evidently showed that transmission of this virus through interactions and exposures. The death toll of these infected patients is increasing day by day especially when they have prehistory fatal diseases like cardiovascular, diabetics, and respiratory diseases. In this review, we summarized and explained the research progressed and available data on epidemiology, COVID-19 phylogenetic relation and its impact of different fatal disease and their relation and discuss the precautionary methods to combat this pandemic. Moreover, the pieces of evidence of spreading the virus through pets and prevention of being spreading by copper metal endorsement.

Vochysia haenkeana extract (Vh-E) was assessed against the neuromuscular blockade induced by Bothrops jararaca venom on chick biventer cervicis (BC) preparation. Pre- and post-venom incubation treatments (Pre-vit and Post-vit) were analysed here. Contractures ACh (110 µM) and KCl (20 mM) were evoked before and after addition of venom without stimulation. Vh-E (600 µg/mL) under Pre-vit was more efficient to neutralize the neuromuscular blockade by venom (40 µg/mL) [72.5±4.6% (venom) vs. 45.2±14% (Vh-E) of blockade, p<0.05, n=4]. Vh-E (600 µg/mL) did not cause significant changes under Post-vit [72.5±4.6% (venom) vs. 63.4±8.2% (Vh-E) of blockade, n=4]. The Pre-vit inhibited the blockade of the contracture to ACh (106±17% of response; n=4) while the Post-vit was able to attenuate the effect of the venom on this contracture (55±5% of response; n=4); related to those contractures to KCl both of treatments with Vh-E attenuated the blocker effect of the venom (62.5±7.7% and 55±5% of response for Pre-vit and Post-vit, respectively; n=4). In conclusion, Vh-E neutralizes partially the neuromuscular blockade in Pre-vit, an effect that can be related to preserved function of “extrinsic” post-synaptic receptors, by measured contractures in response to ACh. The myotoxicity of the venom was significantly reduced by Vh-E in both, Pre-vit and Post-vit, by measured contractures in response to KCl.

This study purposed to study the Preservative agents that are required to ensure that manufactured foods remain safe and unspoiled; work was conducted to evaluate the efficacy of essential oils from two eucalyptus species, Eucalyptus grandis and Eucalyptus crebra in food preservatives; to run this experiment flesh eucalyptus leaves collected from Ruhande Arboretum forest were submitted to hydrodistillation and yields(amount) of 0.38 and 0.34 % for Eucalyptus grandis and Eucalyptus crebra were obtained, respectively. Phaseolus vulgaris, Sorghum condatum, cooked Ipomoea batatas (sweet potatoes) and bread were the sample foods used to assess their preservative efficacy. Acanthoscelides obtectus and Stophilus oryzae were used as pests for Phaseolus vulgaris and Sorghum condatum respectively. For bread and cooked Ipomoea batatas, Rhizopus nigricans are used to assess the efficacy of these two essential oils to inhibit their growth; the obtained results revealed that those essential oils could act as insecticide in the storage of Phaseolus vulgaris and Sorghum condatum. Essential oil from Eucalyptus grandis protected these two foods against pests in the periods of 4 and 9 days, respectively while essential oil from Eucalyptus crebra protected them for the periods of 6 and 11days, respectively.

The age-old battle between plants and viruses has many twists and turns. Plants acquired the RNAi factors to checkmate the viruses and the viruses encode VSRs to defeat RNAi for their own survival. Plants designed mechanisms to neutralize the toxic effects of VSRs and the viruses, in their turn, use host microRNAs to strengthen their infection processes. The infightings between these two entities will take different shapes with prolonged evolution and accordingly the researchers will dig these novel forms of duels not only to throw lights in the involved mechanisms but also to manipulate various antiviral strategies. Some of the research courses that might come up in the immediate future are discussed.

The use of enzyme linked immunosorbent assay (ELISA) for the detection of plant viruses is well documented. It proved to be a very valuable detection tools for the plant viruses. The efficiency of the ELISA technique was for practical purpose independent of the ratio of antibodies to antigen. This avoids the necessity of making specific enzyme conjugates for each antigen to be tested and eliminates the extreme specificity, thus allowing for quantitative evaluation of strain relationships. The advantages of indirect ELISA are sample. It needs only to be macerated and added to the plate. The crude antiserum could be used, although it should be cross absorbed before to prevent spurious host reaction. Single commercially available second antibody conjugate is utilized, thus eliminating the problems of preparing and storing many different conjugated antisera. Blotting technique has become widely used for specific identification of nucleic acid and proteins. This dot assay was modified to detect protein by spotting the antigen on a nitrocellulose membrane and incubating the membrane in test antibody followed by incubation in peroxidase-conjugated second antibody to the first antibody, and by development in 4-chloro-1-naphthol. The above procedure termed dot blot immunobinding assay (DBIA). The technique of tissue blotting on nitrocellulose membrane was described for detection of plant viruses in infected plants. Tissue blots were made by pressing with a firm and gentile force, the freshly cut tissue surface on nitrocellulose membranes. The possibility of using both sides of the nitrocellulose membrane (NCM) by tissue blot immuno assay (TBIA) for the detection plant viruses. In an effort to reduce the cost of virus assays, different types of regular paper were evaluated as possible replacements for the commonly used nitrocellulose membrane (NCM) as the solid phase in the tissue-blot immunoassay (TBIA) were used. Comparisons between different serological methods were demonstrated by many investigators Dot immunobinding was eight times more sensitive for detection of PVX and four times more sensitive for detection of PVS and PVY than DAS-ELISA.

Clarireedia jacksonii sp. nov. Formerly Sclerotinia homoeocarpa F.T. Bennett, the causal agent of dollar spot (DS), is the most destructive pathogen in turfgrass. Symptoms appear as circular patches 10-40 mm in diameter with small tan lesions surrounded by a darker band, sometimes presenting an hour glass appearance. A multi-year study was initiated with the objective of determining the efficacy of biological control agents (BCA) and tank mixes of BCA’s and synthetic fungicides on DS control. Nutrient source was also evaluated to determine any interaction with the BCA’s and tank mixes. in vitro studies evaluated the efficacy of synthetic and BCA’s for C. jacksonii control. Quarter strength potato dextrose agar was amended with ¼, ½ and full labeled rates of various products. Chlorothalonil at all rates provided greatest (> 90%) control of C. jacksonii for study duration. Biological control agents provided best efficacy at ¼ and ½ label rates. Streptomyces griseoviridis provided least efficacy and may have exacerbated formation of C. jacksonii. Preventative field evaluations for synthetic and BCA’s provided different results between two study years. In Year 1, all treatments had < 15% disease severity for the duration of the study. In year 2, disease pressure was extremely elevated. Synthetic program 1, centered on azoxystrobin + propiconazole applications and conventional fertility sources, provided best results with < 5% disease severity for the duration of the study. Reduced synthetic program 1, and synthetic program 2 followed closely with < 10% disease severity. Reduced synthetic programs were based on monthly applications of either chlorothalonil or pyraclostrobin every 30 day, alternated with biofungicide applications. Synthetic program 2 utilized rotation applications of pyraclostrobin and chlorothalonil every 14 days. Organic programs, utilizing only biofungicides and organic fertility sources, provided the least amount of control and exceeded the 15% threshold by the second month of the evaluation period.

Background: Azithromycin (AZM) is a macrolide antibiotic with distinct pharmacokinetic properties and is increasingly used as maintenance treatment in patients with bronchiectasis in order to reduce infectious exacerbations and improve pulmonary symptoms. The exact mechanism of action is not known and the relation between azithromycin dose level, local and systemic drug levels and clinical effect however, has not been extensively studied yet. Objectives: To explore the relation between AZM serum and sputum concentrations, clinical effect parameters and side effects. Methods: Azithromycin concentrations were measured in serum and sputum samples of bronchiectasis patients receiving one year of AZM treatment (250mg OD) enrolled in the Bronchiectasis and Azithromycin Treatment (BAT) trial, a double blind, randomised placebo-controlled trial. Results were correlated with data on AZM dose level, exacerbation frequency, lung function (forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), quality of life and symptoms collected within the same year. Results: 83 sputum samples from 31 patients and 151 serum samples from 43 patients were available for analysis. Mean AZM dose-level ranged from 18.8 to 39.8 mg/kg body weight/ week, generating mean AZM concentrations of 7.57 mg/L (SD 9.49) in sputum and 0.11 mg/L (SD 0.085) in serum. No correlation was found between side effects and AZM dose level, sputum- or serum concentrations. Significant correlation was found between AZM sputum concentration and CRP-level (r= -0.6). Conclusion: High and stable AZM sputum levels were reached during long term treatment, as opposed to low AZM levels in serum. Apart from CRP-levels to AZM sputum concentration, no other outcome parameter showed significant correlation to AZM serum- or sputum levels. AZM dose- or exposure levels were not predictive for the occurrence of side effects.

A term neonate was transferred from a Local Neonatal Unit to our surgical Neonatal Intensive Care Unit on Day 2 due to abdominal distension with radiological appearances suggestive of intestinal obstruction. He was born by Caesarean section with no risk factors for sepsis. He was intubated at birth for increased work of breathing and failed planned extubation on Day 1. 

Six clinical Staphylococcus aureus strains isolated from different clinical samples. Isolates ASIA1 and ASIA2 isolated from urine samples of urinary tract infected patients; ASIA3 isolated from swab samples of burn abscess patients at Assiut University hospital as well as ASIA4, ASIA5 and ASIA6 obtained from blood samples of different cancer patients at South Egypt Cancer Institute. All isolates showed varied abilities to produce halo zones of hydrolysis with different diameters on blood agar, heated plasma agar, casein agar and skim milk agar plates along with different clot lyses percent. Staphylococcus aureus ASIA3, ASIA4 and ASIA6 produced 4.83, 5.98 and 2.08 U/mL of staphylokinase on tryptone soy broth reduced to 1.95, 2.08 and 1.70 U/mL on casein hydrolysate yeast extract broth, respectively. On the other hand, Staphylococcus aureus ASIA1, ASIA2 and ASIA5 gave 2.20, 2.93 and 3.65 U/mL on CYEB compared to 2.10, 1.88 and 3.41 U/mL on TSB as production medium. The staphylokinase yielded from the hyperactive producer Staphylococcus aureus ASIA4 was increased for 7.64-fold (from 2.08 U/mL to 15.88 U/mL) on the optimized fermentation medium composed of 5.0 g sucrose as carbon source, 10.0 g soy bean as nitrogen source, 5.0 g NaCl, K2HPO4 5.0 g and pH 7.0 that inoculated with isolate ASIA4 and incubated for 24 h at 35 °C. Moreover, Staphylokinase activity reached its peak at the optimal enzymatic reaction conditions which were reaction time 25 min, casein as substrate, reaction pH 8.0, reaction temperature 40 °C. In addition it retained 100% of its activity at temperature ranged between 15 and 45 °C and pH ranged from pH 6.0 to 9.0. EDTA inhibited the enzyme activity by 3.0% to 32.2% with increasing its values from 30.0 to 90.0 mM. MgCl2 at a concentration of 30 mM increased the enzyme activity by 4% and then slightly decreased at higher concentrations but NaCl was potent staphylokinase activator at concentrations lower than 90 mM.

Multiple studies have investigated the relationship between androgenetic alopecia and cardiovascular disease, including studies that have identified elevated rates of cardiovascular disease in patients with vertex hair loss, vertex and frontal hair loss, early onset hair loss and rapidly progressive hair loss. In addition, increased risks for hypertension, excess weight, abnormal lipids, insulin resistance, carotid atheromatosis and death from diabetes or heart disease have been reported in this population. Studies investigating an association between androgenetic alopecia and metabolic syndrome have yielded conflicting findings. Distinct guidelines for the detection and prevention of cardiovascular disease in individuals with androgenetic alopecia have not been established. In addition to the traditional risk factors for developing cardiovascular disease, included in the definition of the metabolic syndrome, several skin diseases have recently been shown to be markers of conditions relating to the patient’s overall health. Physicians should be aware of the possible connection between relatively frequent skin diseases, such as psoriasis and hair growth disruptions, including androgenetic alopecia and female pattern hair loss and cardiovascular disease. This review is concentrated on the association between insulin resistance, type 2 diabetes, abdominal fat, cardiovascular disease and hair growth disruptions as an early indicator of these underlying conditions. We have investigated the importance of robust primary clinical treatment measures to address the manifestation of hair loss due to a disruption caused by metabolic syndrome as an effective means to alleviate further stress induced hair loss, which can exacerbate the underlying cause.

A thought-provoking debate in the popular literature concerning vaccination has blossomed in recent years [1-6]. While “traditionalists” support universal immunization against a variety of infectious diseases, many influential individuals hold that vaccinations do far more harm than good. The web sites vactruth.com and anhinternational.org are typical web sites to visit to understand their concerns.  More details on the debate, offering commentary on both sides of the issue, can be explored at wikipedia.org/wiki/Vaccine_controversies. In essence, however, those arguing for the universal use of vaccines point to the many millions of lives saved since mass immunization programs were introduced and further argue that resistance to routine vaccination is almost always based on false information. Those arguing against the routine use of vaccines usually either contend that the vaccines are unsafe (often maintaining that vaccine components such as formaldehyde or thimerosal are highly toxic) or alternately argue that governments simply do not have the moral authority to encroach on an individual’s freedom to make medical decisions for themselves or for their children.

When grouping children with psoriasis depending on TaqI (T/C) genotypes of the VDR gene, the youngest age of disease onset and the longest duration of dermatitis (5.60 ± 0.77 years and 4.90 ± 0.68 years, respectively) showed up in case of the CC genotype. In case of the TT genotype, disease onset coincided with an older age, and the history of present illness was the shortest (10.26 ± 0.64 years and 2.59 ± 0.58 years, respectively). PASI (20.32 ± 3.43) and BSA (40.00 ± 6.11) severity indices were the highest and of statistically significant difference to those in other groups in the presence of the CC genotype. In case of the TC genotype, the index PGA (2.80 ± 0.15) was the lowest and made a statistically significant difference to the values of other groups. A negative correlation between vitamin D levels and the PASI, PGA, BSA was identified in children holding CC and TC genotypes. Conclusion: The clinical presentation of dermatitis and its epidemiological features in children with psoriasis, namely the age of disease onset, duration of exacerbation, body surface area and the intensity of psoriasis symptoms depend on vitamin D serum levels and genotypes of the TaqI polymorphic variant of the VDR gene.

Background: The Islamic religion has emphasized the importance of health and well-being, and Muslims have recognized the value of a good and healthy life based on Islamic recommendations. Health-oriented lifestyle is a multi-dimensional phenomenon that is the purpose of this study to investigate the Islamic lifestyle. Methods: In this review study, we tried to explore practical strategies in Islam through access to credible sources in the form of a descriptive article on achieving a healthy lifestyle in nutrition. For this purpose, using keywords and electronic and manual searches in authentic Islamic and medical sources, information was searched and collected to answer the research question. Results: Based on the results of the reviewed studies, the guidelines of Islamic religion and beliefs are mainly based on improving lifestyle factors and dietary habits. It has been emphasized that adherence to the Islamic dietary guidelines and lifestyle, may lead to less risk of diseases. Conclusion: Given the availability of valuable nutritional resources and instructions in Islam to prevent and combat nutrition-related diseases, these theories can be applied and prevent from spreading and creating malnutrition-related diseases; the guidelines of Islam on healthy lifestyles in nutrition can be recommended to the world as a basic strategy

Sleep is considered as a complex process in human beings and is least understood mechanism. Role of sleep in synaptic plasticity remains a debatable topic till date. Sleep is influenced by genetic background of the individual. EEG done in human sleep showed strong influence of genetic factors. A handful of familial analyses involving specific gene loci and twin studies has been done in this regard. In this review article focused discussion on genetic contribution to sleep phenotypes, twin and familial linkage studies and effect of genetic variation on sleep will be covered

Background: Thrombotic microangiopathy (TMA) is a rare and life-threatening complication of prostate carcinoma. Whether plasma exchange has a role in treatment remains a subject of debate. Here we present a case followed by a systematic review of the literature on this subject. Case report: We describe a 69-year old patient presenting with TMA, which was associated with an underlying metastatic prostate carcinoma. We conducted a search of similar cases in literature. Results: Our patient was treated and responded well on plasma exchange. Systematic review of the literature showed 17 additional cases of TMA associated with prostate carcinoma of which eleven were treated with plasma exchange with mostly good response. Conclusion: Based on current data we cannot exclude a potential role for plasma exchange in prostate cancer associated TMA.

The Coronavirus disease-2019 (COVID-19), has become a worldwide pandemic and the scientific communities are struggling to find out the ultimate treatment strategies against this lethal virus, Severe Acute Respiratory Syndrome Coronavirus–2 (SARS-CoV-2). Presently, there is no potential chemically proven antiviral therapy available in the market which can effectively combat the infection caused by this deadly virus. Few vaccines are already developed but it is not clear to the scientific community how much efficient they are to combat SARS-CoV-2. Mode of transmission and symptoms of the disease are two important factors in this regard. Rapid diagnosis of the COVID-19 is very much important to stop its spreading. In this scenario, a complete study starting from symptoms of the disease to vaccine development including various SARS-CoV-2 detection techniques is very much required. In this review article, we have made a partial analysis on the origin, virology, global health, detection techniques, replication pathways, doses, mode of actions of probable drugs, and vaccine development for SARS-CoV-2.

Foreign body ingestion in children is a serious problem encountered among children. Approximately 80% of cases of foreign body ingestions occur in children between the ages of six months and three years [1]. Button battery ingestion occurs at an estimate rate of ten in one million people per year, a small group of which are retained in the esophagus and later become complicated [2]. Button battery ingestion can lead to esophageal perforation and death within hours if not appropriately diagnosed [3].

Introduction: The tendency to impulsive behaviors and/or violence is exacerbated after alcohol consumption. Still, the relation between alcohol/violent deaths reported in the literature is not accurate, and in general, alcohol is only seen as a trigger to aggressive actions. The relationship of the victims with their blood alcohol is less studied. They were especially concerned about the role of alcohol as a risk factor for victims of unnatural death. Thus, our goal is to check the influence of alcohol in victims of violent deaths as homicides, suicides, and accidents. Materials and methods: Retrospectively the medical records of 805 autopsies performed at the Institute of Forensic Medicine (IML) of Franco da Rocha, in the period 2001 to 2017 were reviewed. The variables studied were sex, age, types of violent death rates, and alcohol - these were considered positive when above 0.3 mg/ml. The dosage of blood alcohol concentration (BAC) was performed using samples of 10 ml of blood collected at necropsy, is preferably taken from the cardiac chambers or of the right femoral vein. Dosages of alcohol in blood samples were done in the Forensic Toxicology Center of the IML by gas chromatography, using the technique of separation “headspace” and double column. Results: Drug testing for alcohol was available for 488 (79.1%) of 617 necropsies. Of the 617 subjects studied, 532 (85.7%) were male, and 85 (13.8%) were females (with high rates of adolescents). The vast majority (n = 230) were killed, and 40.5% of victims had BAC above 0.3 mg/ml of blood. Traffic accidents came next, accounting for 181 deaths, with 41% of victims presenting positive BAC. Discussion: High blood alcohol levels of the victims were associated mainly with the genesis of accidents (drowning, falls, traffic, aspiration/ smothering) and murder (with impaired ability to resist or by causing the release of impulses to engage in violent situations), about 40% of cases. Conclusion: Our results indicate that alcohol abuse is a risk factor for victims of violent death. In these cases, alcohol has two types of action. Direct: contributes to accidents of various kinds - from traffic by decreasing powers of concentration, attention, and loss of reflexes, to other types of accidents such as drowning, falls, swallowing disorders causing airway obstruction, and mechanical asphyxia. And they were indirect, making it easier for individuals to engage in conflict (and thus become victims of crimes).

Introduction: A dermoid cyst is a developmental choristoma lined with epithelium and filled with keratinized material arising from ectodermal rests pinched off at suture lines. These are the most common orbital tumors in childhood. They are categorized into superficial and deep. Superficial orbital dermoid tumors usually occur in the area of the lateral brow adjacent to the frontozygomatic suture. Infrequently a tumor may be encountered in the medial canthal area [1], which is the second most common site of orbital dermoids. We report a case where a swelling presented in the medial canthal area without involving the lacrimal system. Case report: A 43 year old lady presented with complaint of swelling near the (RE; Right eye) since 2 years duration. She presented with a solitary 1.5 cm x 1 cm ovoid, non-tender, non-pulsatile, firm, non-compressible mobile swelling with smooth surface over the medial canthus of right eye. (MRI; Magnetic Resonance Imaging) brain and orbit showed right periorbital extraconal lesion and the (FNAC; Fine Needle Aspiration Cytology) suggested of Dermoid Cyst. RE canthal dermoid cyst excision was done under Local Anasthesia. Conclusion: Complete surgical excision in to be treatment of choice for dermoids. Since medial canthal mass can involve the lacrimal system, it becomes necessary to perform preoperative assessments using (CT; Computed Tomography), MRI or dacryocystography while planning the surgical approach. Silicone intubation at the beginning of the surgery is an easy and effective way of identifying canaliculi and of preventing canalicular laceration during dermoid excision if the lacrimal system is found to be involved.
