Canine Distemper Virus detection based in Hemaglutinine Gene as target in Reverse Transcriptase-Polymerase Chain Reaction

Published on: 27th December, 2018

OCLC Number/Unique Identifier: 7964755439

Canine Distemper have become a major concern within the veterinary clinical work. Thus, the appearance of many cases of canine distemper in adult animals with their vaccination plan up to date has alarmed veterinarians. Many cases of canine distemper have become a major concern within the clinical veterinary task. The purpose of this work was to detect the gene of hemagglutinin of the virus canine distemper, by using the Polymerase Chain Reaction associated with Reverse transcription (RT-PCR), as confirmation of the clinical diagnosis of disease. For this, peripheral blood samples of animals were used clinically patients and were grouped according to their date of extraction and using vaccines commercial as control. The results allow to demonstrate a high sensitivity of the technique, besides allowing the use of samples up to seven days of storage at 4°C, despite the fragility of RNA viral. Detection of canine distemper virus haemagglutinin gene in field samples and its high sensitivity, suggests studying its use as a diagnostic tool complementary to the clinical diagnosis of canine distemper in our country.

External Root Resorption associated with Impacted Third Molars: A Case Report

Published on: 26th April, 2017

OCLC Number/Unique Identifier: 7286358319

The indications for impacted third molar extraction include the prevention of dental reabsorption on the adjacent tooth. Resorption can be classified as physiological (when deciduous teeth are exfoliated) or pathological (when caused by injury or irritation to the periodontal ligament). Many causes can trigger external root resorption (ERR), the most common cause of which is orthodontic forces. The most common cases of ERR involve impacted third molars which, due to the lack of space for their eruption, generate a greater chance of ERR on the distal portion of the second molar. This pathology is becoming progressively more frequent in clinical dental care. Periapical and panoramic radiographs are used to aid in diagnosis, as is cone beam computed tomography. In cone beam computed tomography scans, radiolucent areas with irregular gaps are detected; these gaps represent a significant loss of dental material. The objectives of this article were to report a case of second molar resorption triggered by an impacted third molar and to perform a review of the literature on the causes of external root resorption. Ideally, this information will aid dental clinicians (and orthodontists in particular) in understanding the features of this pathology so that they may recommend preventive third molar extraction when necessary.

Enamel demineralization with resin modified gic and conventional composite resin - a comparative in vivo study

Published on: 31st July, 2017

OCLC Number/Unique Identifier: 7286352515

Background & Objectives: Fluoride releasing bonding agents can help the orthodontist to minimize enamel demineralization independent of patient cooperation. This in vivo study was conducted to evaluate the efficacy of resin modified glass ionomer cement (RMGIC) on reducing enamel demineralization around orthodontic brackets and confirm the superior caries-preventive effect of RMGIC by assessing the mutans streptococci (S. mutans) in plaque samples in vitro. Methods: 60 subjects (aged 14-20 years) scheduled to have premolar extractions as part of the orthodontic treatment plan were selected and randomly divided into 2 groups of 30 each (group 1: the brackets were bonded on the teeth using light cure composite resin and group 2: the brackets were bonded using RMGIC). Plaque scores (modification of plaque index by Silness and Loe) were recorded and plaque samples were collected before bonding, one week and one month after bonding. S.mutans colonies were recorded from the plaque samples inoculated on MSB agar plates, incubated under 95% N2 and 5% CO2 for 48 hours at 370C in a CO2 jar. After 1 month, the right maxillary and mandibular first premolars were debonded, extracted and depth of enamel demineralization area was estimated using polarized light microscope. Results: After statistical analysis, a significantly higher mean depth of demineralized lesions was noticed in group 1 as compared to group 2. A significant difference between occlusal and gingival depth was seen only in group 2, thus illustrating a wedge effect. In group 1, a statistically significant increase in the mean colony forming units (CFU) of S.mutans has been noticed at different time intervals whereas in group2, a significant increase was observed only at 1month. Unlike at 1 month, a statistically significant difference in mean CFU between group 1 and group 2 has been observed at 1 week (P<0.05). Conclusions: Enamel lesions adjacent to the bracket base on teeth bonded with the RMGIC were smaller than those on teeth bonded with a composite resin. The high “burst effect” of fluoride release for the first few days of RMGIC after bonding is confirmed by statistically significant reduction in CFU counts of S. mutans in plaque.

Osteogenic Accelerated OrthodonticsTM for treatment of a Skeletal Class II patient with moderate crowding

Published on: 18th September, 2017

OCLC Number/Unique Identifier: 7286353388

Introduction: A 17 years old male patient was treated at the University orthodontic department. He had the chief complaint of unaesthetic appearance of his teeth, mostly for anterior crowding. The pretreatment records showed a Class II skeletal relation, moderate upper and lower anterior crowding, 0.5mm of overbite and 2mm of overjet. Materials and Methods: It was suggested Osteogenic Accelerated Orthodontics (OAOTM), the treatment option was very attractive to the patient although it required a surgical procedure and a more expensive type of treatment. Results: The overall treatment time was 6 months, facial balance was improved and the final occlusal relationships from the functional and aesthetics perspective were good. Conclusion: OAOTM is a good alternative to reduce extractions rate as it increases the scope of tooth movement and strengthen the periodontal tissues thru bone grafting, although these claims require more scientific data to be validated.

Corticotomy facilitated correction of skeletal class II malocclusion

Published on: 26th October, 2017

OCLC Number/Unique Identifier: 7379412270

Selective alveolar decortication and periodontal augmentation with a bone graft were the two procedures used for the correction of the skeletal class II malocclusion in the case reported. A 25-year-old male patient presented with a skeletal class II malocclusion with increased bi-maxillary dento-alveolar protrusion, increased overjet, deep bite and imbricated and rotated mandibular incisors with bilateral presence of supernumerary teeth in the maxillary right and left premolar regions. Extraction of supernumerary in the maxillary right and left premolar region, and impacted UL5 was done. Pre-adjusted edgewise appliance, Roth’s prescription (0.022x0.028-inch slot), was bonded and a week later full thickness labial and lingual flaps were reflected in the maxillary and mandibular arches. Circumscribed corticotomy cuts was done and subsequently augmented with a bone graft. Orthodontic treatment was commenced immediately after surgery and orthodontic adjustments were performed every 2 weeks. The entire orthodontic treatment was completed in 9 months. Regional acceleratory phenomenon, triggered by the alveolar decortication, was responsible for the rapid correction of the malocclusion and the augmentation with the bone graft provided adequate bone volume for housing the teeth, thereby decreasing the possibility of subsequent relapse.

Evaluation of novel culture media prepared from plant substrates for isolation and identification of Cryptococcus Neoformans Species Complex

Published on: 14th August, 2018

OCLC Number/Unique Identifier: 7844645048

Background: Melanin production due to phenoloxidase activity is a distinctive property of Cryptococcus neoformans and Cryptococcus gattii species complex yeasts. Therefore, an agar medium containing a precursor of melanin pigment is potentially useful to identify and differentiate cryptococcal colonies from other yeasts. Background: This study aimed to evaluate and compare the ability of Cryptococcus neoformans species complex isolates to produce brown-pigmented colonies when grown on media prepared from various plant leaves or seeds extracts. Material and Methods: Forty-six C. neoformans species complex isolates which were obtained from various environmental and clinical samples were inoculated on different media containing coriander, cumin, soybean, lupine, flax, pumpkin, basil, peppermint, and marjoram, were observed for the rate of growth and pigment production during a five-day period. Results: All isolates were pigmented on all media within 24-48 hours, and brown or dark brown colonies were observed in less than five days, while C. albicans grew but did not produce any pigment. Conclusion: The differential media tested in the present study are simple and inexpensive, and represent alternative valid tools for presumptive identification of C. neoformans species complex from clinical and environmental samples

A Review on filaricidal activity of phytochemical extracts against filariasis and the Parasites Genomic Diversity

Published on: 26th October, 2018

OCLC Number/Unique Identifier: 7912403155

Filariasis is one of the Neglected Tropical Diseases (NTDs) known to be of serious public health importance and pose devastating socio-economic burden especially among the poor people in tropical and subtropical countries of the world. The parasite is responsible for lymphatic filariasis affecting about 1.3 billion people in 72 countries worldwide. The major parasitic agents of the infection are three closely related nematodes of clade Onchocercidaei namely Wuchereria bancrofti, Brugia malayi and B. timori that are transmitted to human through bites by mosquitoes of genera: Aedes, Anopheles, Culex and Mansonia. The disease is targeted by the World Health Organization (WHO) for elimination by 2020 through the use of chemically synthesized drugs used as therapeutic agents to cure the disease but there are some setbacks. Phytochemical extracts are viewed as alternative therapy in the management of the disease. Additionally, the species have many ecological variants and are diversified in terms of their genetic fingerprint. This diversification in terms of genomic sequences as well as rapid infection rate warrant the lymphatic filarial parasites to respond differently to diagnostic and therapeutic interventions. Thus understanding the genomic diversity of the parasite will help in efficient therapeutic management of the disease, thereby eliminating it to prevent unnecessary suffering and contribute to the reduction of poverty. In this review, we have highlighted on the used for phytochemical extracts in the therapeutic management of the lymphatic and the molecular genetic diversity of the parasite was delineated.

Hypoglycemia by Ginseng in type 2 Diabetic Patient: Case Report

Published on: 9th February, 2017

OCLC Number/Unique Identifier: 7317650902

Ginseng extracts are often used as adaptogen to improve mental performances and well being, helping to overcome stress. Thus, in our times a lot of ginseng extracts are continuously produced and sold into commercial channels. Both Asian and Korean red ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) are the most extensively used and researched. Both Panax ginseng and Panax quinquefolium contain different types of saponins, also known as ginsenosides, which are the substances that give ginseng medicinal properties. Human and animal studies showed that ginseng extracts can also have hypoglycemic effects. The mechanisms by which ginseng reduces blood glucose levels are unclear; some mechanisms have been proposed to explain its hypoglycemic effect, especially modulating effects on insulin sensitization and/or insulin secretion and regulating actions on digestion and intestinal absorption. We describe a case of hypoglycemia by ginseng in type 2 diabetic patient treated with oral hypoglycemic agents. Although, in order to provide better assessments of a sure anti-diabetic efficacy of ginseng, larger and longer randomized controlled clinical trials will be required, in our case we think that we have enough evidence to believe that the cause of hypoglycemia was ginseng. Obviously, this report should not be taken as a proof of the hypoglycemic effect of ginseng, nor it wants to be a suggestion to use ginseng in the treatment of diabetes; instead, it wants to be an alert for patients and clinicians to avoid hypoglycemia in daily clinical practice.

Anti-anxiety effects in mice following acute administration of Ficus Thonningii (wild fig)

Published on: 11th September, 2018

OCLC Number/Unique Identifier: 7856121803

The effect of acute administration of ethanol extract of F. thoningii on anxiety and fear in Swiss white mice was studied. 30 adult Swiss white mice of both sexes were randomly divided in to three groups of 10 mice each. Group1 served as the control and was administered normal saline only. Group 2 (low dose group) was administered 10mg/kg ethanol extract of the F. thoningii, while group 3 (high dose group) was given 20mg/kg of the same extract. All animals were allowed food and water ad libitum. Neurobehavioral parameter was assessed using the light/dark transition box. The analysis of variance (ANOVA) was used to test for variability within and among groups. Results were expressed as Mean ±SEM (standard error of the mean) and probability level p<0.05 was accepted as significant. The result showed that the frequency of transition in the light/dark transition box was significantly increased in the test groups (p<0.05; p<0.01).Similarly, the Light Box Duration was also significantly increased (p<0.01) in the low and high dose groups respectively. However, the Dark box duration was significantly decreased (p<0.05; p<0.01) in the low and high dose groups compared to control. This index showed a decreased level of anxiety and fear in the test groups. This was followed by a corresponding trend of decreased frequency of stretch attend posture and duration of freezing in the light/dark transition box (p<0.01; p<0.001) compared to the control. Summarily, acute administration of ethanol extract of F. thonningii causes calmness and sedation in moderate and high doses. It is therefore likely that it reduces aggression. If the result from this finding is extrapolated to humans, F. thoningii could be used to reduce anxiety disorders.

Expression of C-type Natriuretic Peptide and its Specific Guanylyl Cyclase-Coupled Receptor in Pig Ovarian Granulosa Cells

Published on: 22nd August, 2018

OCLC Number/Unique Identifier: 7844580667

Background: C-type natriuretic peptide (CNP) was isolated from porcine brain and is a 22-amino acid peptide which belongs to the natriuretic peptide (NP) family. Even though this peptide shares structural similarity to other endogenous NPs including atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) its receptor selectivity is different from other NPs. The present study was undertaken to investigate the expression of C-type natriuretic peptide (CNP) and its specific guanylyl cyclase (GC)-coupled receptor in the granulosa cells of the pig ovarian follicle. Results: Specific 125I-[Tyr0]-CNP(1-22) binding sites were localized in the granulosa cell layer of the ovarian follicle with an apparent dissociation constant (Kd>) and a maximal binding capacity (Bmax) of 1.41±0.39 nM and 2.75±0.65 fmol/mm2 respectively. Binding of 125I-[Tyr0]-CNP(1-22) to these sites was also prevented by atrial natriuretic peptide (ANP(1-28)), brain natriuretic peptide (BNP(1-26)) and des[Gln18,Ser19,Gly20, Leu21,Gly22] ANP(4-23) (C-ANP). Production of 3’,5’-cyclic guanosine monophosphate (cGMP) by particulate GC in the granulosa cell membranes was stimulated by natriuretic peptides (NPs) with a rank order of potency of CNP(1-22)>>BNP(1-26)>ANP(1-28). HS-142-1, a selective antagonist of the two recognized GC-coupled NPRs, inhibited CNP(1-22)-stimulated cGMP production in granulosa cell membranes in a dose-dependent manner. Also mRNAs for all three recognized NPRs were detected in granulosa cells using reverse transcriptase-polymerase chain reaction (RT-PCR). Serial dilution curves of granulosa cell extracts were parallel to the standard curve of synthetic CNP. Conclusion: These results indicate that CNP and its specific receptor are expressed in the granulosa cells of the pig ovary, and suggest that CNP may be a local autocrine and/or paracrine regulator via activation of its specific GC-coupled receptor, NPR-B.

Medicinal plant Potentilla fulgens and its effect in vitro against Fasciola gigantica

Published on: 13th May, 2021

OCLC Number/Unique Identifier: 9272395334

Fascioliasis is a one of the most important serious parasitic zoonotic disease which caused by trematode giant liver fluke Fasciola hepatica and F. gigantica among cattle’s and humans. The infection of Fasciola can be control by the use of phytochemicals as anthelmintic components. The anthelmintic activities of dried root powder of medicinal plant Potentilla fulgens and their different preparations (organic extracts and column purified fraction) are uses in vitro against liver fluke F. gigantica. The dried root powder, different organic extract, and column fractions were time and concentration-dependent. Among all the organic extracts, ethanol extract was high toxic than other organic extracts. The toxic effect of ethanolic extract of P. fulgens after 2h exposure the LC50 value is 5.22 mg/ml against F. gigantica. The column purified fraction of dried root powder of P. fulgens shows more toxicity. The 2h LC50 of column purified fraction was 3.25 mg/ml whereas in 8h exposure the LC50 is 1.24 mg/ml. The phytochemicals of the P. fulgens may be used as anthelmintic components against liver fluke F. gigantica.

Impact of coronavirus pandemic on safety and time of administration of subcutaneous immunotherapy among pediatric patients

Published on: 2nd September, 2022

OCLC Number/Unique Identifier: 9617323801

Introduction: Allergen immunotherapy is the only targeted therapy that can modify the natural course of allergic diseases. In pediatric patients, SCIT with aeroallergens is an effective treatment and should be considered as a preventive strategy in the treatment of allergic diseases, even though one of the major concerns about it is its safety. The main purposes of this study were to assess the safety of SCIT ultra-rush schedules with polymerized extracts in a pediatric population and to determine the impact of the COVID-19 pandemic on the safety and time of administration of subcutaneous immunotherapy among pediatric patients.Methods: A retrospective medical records review of patients under 18 years of age undergoing SCIT was made and re-scheduling due to restrictions imposed by the COVID-19 pandemic was recorded. Results: A total of 192 pediatric patients were included. Fifty-nine (31%) had local reactions and systemic reactions were not reported. In March 2020, the first case of COVID-19 was diagnosed in Portugal and all non-urgent appointments and procedures were postponed. In our group of pediatric patients, 43 (22%) were referred to primary care, 38 (20%) stopped AIT definitively and 111 (58%) maintained administrations in the hospital. Only 2 (2%) of them had reactions upon reinitiation. Conclusion: In this study, the ultra-rush protocol using polymerized extracts was safe in pediatric patients. Although the effectiveness of AIT may be compromised due to prolonged suspension of the treatment, it is important to note that despite longer interruptions, administrations may continue without compromising safety, maintaining shorter visits and a lower number of injections.

Determination of the in vivo activity of leaves extract of Zanthoxylum Chiloperone var. Angustifolium (Tembetary hú) orally and intralesionally administered to BALB/c mice experimentally infected with Leishmania

Published on: 23rd November, 2022

Natural products are becoming increasingly important as an unlimited source for obtaining chemical substances with possible pharmacological potential. Current existing drugs for the treatment of cutaneous leishmaniosis produce major side effects; therefore the search for new drugs is justified. The stem bark of Zanthoxylum chiloperone var. Angustifolium Engl. (Rutaceae) is traditionally used in Paraguay for its antiparasitic properties. The leaf extract was evaluated for the first time to determine its leishmanicidal activity in BALB/c mice infected with amastigote forms of Leishmania amazonensis (PH8). The mice were treated orally with the extract at three concentrations (100, 50 and 10 mg/mL), intralesional (50 mg/mL), and subcutaneously using glucantime as a control (100 mg/mL). The percentage of decrease in parasite load was measured and with intralesional 50 mg/kg a reduction of 72% occurred, with the reference drug (Glucantime) a reduction of 62% was obtained with the same oral dose a reduction of 50%, while with an oral dose of 10 mg/mL the percentage of reduction was 55%. When the oral dose was increased to 100 mg/mL, the reduction percentage of the parasitic load was only 16%. These results indicated that the leaf extract of Z. chiloperone var. angustifolium Engl. at low oral concentrations (50 and 10 mg/mL) had very good activity against L. amazonensis, and it was even more efficacious intralesionally at 50 mg/mL but at the oral dose of 100 mg/kg has very reduced antiparasitic activity. This study showed the efficacy of the extract leaves of Z. chiloperone in reducing the parasite load in an in vivo test, so its use as a potential leishmanicidal could be suggested to develop and evaluate new drugs for the oral treatment of leishmaniosis disease with fewer side effects and lower cost.

Evolution of Antifungal Activity of Artemisia herba-alba Extracts on Growth of Aspergillus sp. and Rhizopus sp.

Published on: 11th February, 2025

Plant extracts and their constituents have a long history as antifungal agents, but their use in biotechnology as preservatives, due to the increasing resistance of fungi to fungicides, has been rarely reported in Libya. The aim of this study is to evaluate the antifungal activity of ethanol extract and water extract of the wild native plant Artemisia herba-alba against two genera of mold fungi Aspergillus sp. and Rhizopus sp. This mold fungal causes significant damage to crops in the field or during storage. In this study, a hot ethanol extract was prepared using a device Soxhlet, and water extract hot as well as a cold ethanol extract and cold-water extract aqueous extract three concentrations (25% - 50% - 75%) of plant extracts were used on the tested fungi. All extracts showed an effect on the tested fungi. The concentrations of (75% - 50%) of the extracts had an effect on the tested fungi, while most concentrations of 25% of the extracts did not record any effect on the tested fungi. The hot ethanol extract of the Artemisia herba-alba plant was more effective than the other extracts. Aspergillus sp. was recorded with the highest inhibitory zone (0.73 mm).

Unusual Complications of a Dental Prosthesis Esophageal Foreign Body: About a Case

Published on: 16th April, 2025

Foreign bodies of the esophagus are part of the traumatic emergencies in ENT. They are most often encountered in children, whereas in adults they occur in a particular context and are rarely overlooked.This was a 48-year-old patient from a neighboring country referred by a colleague for a history of neglected laryngeal contusion with infectious cervical fistula evolving for 2 years. Further questioning revealed a notion of accidental ingestion of dentures. The first endoscopy was of capital interest in especially in the diagnosis and management of this long-retained foreign body. The extraction under general anesthesia was done by a combined endoscopic and external approach. The postoperative course was marked by superinfection and swallowing disorders.Cervical suppurations secondary to esophageal foreign bodies are rare, especially in adults. Clinicians should consider this possibility in the face of any chronic cervical suppuration that resists treatment.

Bilateral Severe Encrustation of Long-Term Indwelling Double-J Stents in a Young Non-Lithiasic Patient

Published on: 16th March, 2026

Ureteral double-J stents are a commonly used device in urological practice to allow urinary drainage, avoid ureteral obstruction processes, and protect the upper urinary tract after surgical procedures. However, long indwelling time may give rise to numerous complications, such as infection, migration, and fragmentation of the stent, especially encrustation. Encrustation of stents is a well-known complication that has been closely related to the time active of the stent and can cause significant morbidity if not timely addressed. In severe cases, abundant mineral deposition can result in the development of large calculi encasing the stent and rarely progress to staghorn stones. These cases may pose challenges in terms of the extraction of the stent and may result in complex endourological intervention. The encrustation likelihood is substantially higher if stents are left forgotten or remain in place longer than the advised period. Most patients with heavily encrusted stents have symptoms including flank pain, urinary tract infection, hematuria, or obstructive uropathy, but can present without any symptoms, and this can delay the diagnosis.
