Relation of radial artery occlusion after trans-radial percutaneous coronary intervention with the duration of hemostatic compression

Background: Trans-radial percutaneous coronary intervention (PCI) in cardiac procedures accesses coronary arteries through the wrist's radial artery. Post-PCI, hemostatic compression on the radial artery prevents bleeding and aids healing. Radial artery occlusion (RAO), a possible complication, involves blockage of the radial artery. This study aimed to assess the relationship between radial artery occlusion after trans-radial percutaneous coronary intervention with the duration of hemostatic compression. Methods: This prospective observational study was conducted in the Department of Cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, spanning from September 2018 to August 2019. The study enrolled 140 patients who underwent percutaneous coronary intervention (PCI) through the trans-radial approach (TRA), randomly assigned to two groups: Group I (2-hour hemostatic compression after PCI) and Group II (6-hour hemostatic compression post-procedure). Data analysis was performed using SPSS version 23.0. Results: In this study, early radial artery occlusion was observed in 4.3% of patients in group I and 12.8% in group II (P=0.04), while late radial artery occlusion occurred in 2.8% of patients in group I and 11.4% in group II, with a statistically significant difference (P=0.04). Multivariate logistic regression analysis identified a 6-hour hemostatic compression duration (P=0.01), post-procedural nitroglycerine use (P=0.03), and procedure time (P=0.03) as predictors of radial artery occlusion. Conclusions: Reduced hemostatic compression duration is linked to a decreased occurrence of both early and late radial artery occlusion following trans-radial intervention.

Versatility and modifications of the cross-finger flap in reconstruction of digital soft tissue defect

Background: Hand injuries can cause major functional and cosmetic concerns. The cross-finger flap (CFF) is an effective treatment for complex finger defects. While CFF has typically been employed to treat volar aspect abnormalities, new versions now address a larger variety of digital soft tissue defects. The aim of the study was to evaluate the clinical outcome of various modified techniques of cross-finger flap which are used to reconstruct different soft tissue defect of fingers. Methods: This was a prospective observational study carried out in the department of Burn and Plastic Surgery at Dhaka Medical College Hospital, Dhaka from September 2018 to February 2020. Forty (40) patients who presented with different soft tissue defect of fingers included in this study according to inclusion and exclusion criteria. Results: The study involved predominantly male participants (80%), with a mean age of 31.70�.28 years. The most common soft tissue defect site was the volar area (47.5%), and various modified cross-finger flap techniques were employed. The majority of patients achieved excellent functional outcomes, with 82.5% classified as good, 12.5% as satisfactory, and 5.0% as poor. Conclusions: The modifications of the cross-finger flap are versatile and useful for different sites of digital injuries with good functional outcome.

Dietary habits of lesser bandicoot rat (Bandicota Bengalensis) in an agro-ecosystem, Pothwar Plateau, Pakistan / Hábitos alimentares de rato bandicoot (Bandicota Bengalensis) em um agroecossistema do Planalto de Pothwar, Paquistão

Abstract Dietary habits of bandicoot rats (bandicota bengalensis) were investigated in the agricultural crops of the Pothwar Plateau, Pakistan by analysing stomach contents. The research activities were conducted in major field crops including wheat-groundnut and in the fallow lands during non-crop season at the field boundaries. The specimens were captured from the fields using kill/snap traps, and dissected to collect their stomach samples for laboratory analysis. Light microscopic slides of the plant material were recovered from stomach samples and the reference materials were collected from the field. Results revealed that the bandicoot rat predominantly fed upon cultivated crops during cropping season but consumed wild vegetation during non-cropping season. There was no significance difference between summer and winter diets. Most frequently consumed crop food items were wheat (Triticum aestivum; 28.57%), groundnut (Arachis hypogea; 11.26%), sorghum (Sorghum bicolor; 10.17%), chickpea (Cicer arietinum; 9.52%), maize (Zea mays; 6.49%), millet (Pennisetum glaucum; 5.84%), barley (Hordeum vulgare; 4.98%) and mustard (Brassica campestris; 4.98%). Among wild vegetation were consumed khbal gha (Cynodon dactylon; 7.79%), baron dhab (Demostachya bipinnata; 7.36%) and Prickly flower (Achyranthes aspera; 3.03%). The study concludes that, in addition to consuming wheat and groundnut crops, the Lesser bandicoot rat also subsists on grasses, weeds, and some fodder crops, as important component of its diet in agro-ecosystem of the Pothwar Plateau.

Resumo Os hábitos alimentares de ratos bandicoot (Bandicota bengalensis) foram investigados nas plantações agrícolas do planalto de Pothwar, Paquistão, por meio da análise do conteúdo estomacal. As atividades da pesquisa foram conduzidas nas principais culturas de campo, incluindo trigo e amendoim, e em terras de pousio durante a estação não agrícola nos limites do campo. Os espécimes foram capturados dos campos usando armadilhas kill/snap e dissecados para coletar suas amostras de estômago para análise laboratorial. Lâminas de microscopia de luz do material vegetal foram recuperadas de amostras de estômago; os materiais de referência foram coletados no campo. Os resultados revelaram que o rato bandicoot alimentava-se predominantemente de culturas cultivadas durante a época de cultivo, mas consumia vegetação selvagem durante a época de não colheita. Não houve diferença significativa entre as dietas de verão e inverno. Os alimentos agrícolas mais frequentemente consumidos foram trigo (Triticum aestivum; 28,57%), amendoim (Arachis hypogea; 11,26%), sorgo (Sorghum bicolor; 10,17%), grão de bico (Cicer arietinum; 9,52%), milho (Zea mays; 6,49%), milheto (Pennisetum glaucum; 5,84%), cevada (Hordeum vulgare; 4,98%) e mostarda (Brassica campestris; 4,98%). Entre a vegetação silvestre foram consumidos khbal gha (Cynodon dactylon; 7,79%), barão dhab (Demostachya bipinnata; 7,36%) e flor espinhosa (Achyranthes aspera; 3,03%). O estudo conclui que, além de consumir culturas de trigo e amendoim, o rato bandicoot pequeno também subsiste de gramíneas, ervas daninhas e algumas culturas forrageiras, componentes importantes de sua dieta no agroecossistema do planalto de Pothwar.

Drinking water quality of various sources in Peshawar, Mardan, Kohat and Swat districts of Khyber Pakhtunkhwa province, Pakistan / Qualidade de água potável de váris fontes dos distritos de Peshawar, Mardan, Kohat e Swat da província de Khyber Pakhtunkhwa, Paquistão

Abstract The present study involves the chemical and bacteriological analysis of water from different sources i.e., bore, wells, bottle, and tap, from Peshawar, Mardan, Swat and Kohat districts of Khyber Pakhtunkhwa (KP) province, Pakistan. From each district, 50 water samples (10 samples from each source), regardless of urban and rural status, were collected from these sources and analysed for sulphates, nitrates, nitrites, chlorides, total soluble solids and coliforms (E. coli). Results indicated that majority of the water sources had unacceptable E. coli count i.e.> 34 CFU/100mL. E. coli positive samples were high in Mardan District, followed by Kohat, Swat and Peshawar district. Besides this, the some water sources were also chemically contaminated by different inorganic fertilizers (nitrates/nitrites of sodium, potassium) but under safe levels whereas agricultural and industrial wastes (chloride and sulphate compounds) were in unsafe range. Among all districts, the water quality was found comparatively more deteriorated in Kohat and Mardan districts than Peshawar and Swat districts. Such chemically and bacteriologically unfit water sources for drinking and can cause human health problems.

Resumo O presente estudo envolve a análise química e bacteriológica de água de diferentes fontes, ou seja, furo, poços, garrafa e torneira, dos distritos de Peshawar, Mardan, Swat e Kohat da província de Khyber Pakhtunkhwa (KP), Paquistão. De cada distrito, 50 amostras de água (10 amostras de cada fonte), independentemente do status urbano e rural, foram coletadas dessas fontes e analisadas para sulfatos, nitratos, nitritos, cloretos, sólidos solúveis totais e coliformes (E. coli). Os resultados indicaram que a maioria das fontes de água tinha uma contagem inaceitável de E. coli, ou seja, > 34 UFC / 100 mL. As amostras positivas para E. coli foram elevadas no distrito de Mardan, seguido por Kohat, Swat e distrito de Peshawar. Além disso, algumas fontes de água também foram contaminadas quimicamente por diferentes fertilizantes inorgânicos (nitratos/nitritos de sódio, potássio), mas em níveis seguros, enquanto os resíduos agrícolas e industriais (compostos de cloreto e sulfato) estavam em níveis inseguros. Entre todos os distritos, a qualidade da água foi considerada comparativamente mais deteriorada nos distritos de Kohat e Mardan do que nos distritos de Peshawar e Swat. Essas fontes de água química e bacteriologicamente impróprias para beber podem causar problemas à saúde humana.

Therapeutic potential of stem cell and melatonin on the reduction of CCl4-induced liver fibrosis in experimental mice model

Abstract Liver fibrosis is initial stage of any chronic liver disease and its end stage is develops into cirrhosis. Chronic liver diseases are a crucial global health issue and the cause of approximately 2 million deaths per year worldwide. Cirrhosis is currently the 11th most common cause of death globally. Mesenchymal stem cell (MSCs) treatment is the best way to treat acute and chronic liver disease. The aim of this study is to improve the therapeutic potential of MSCs combined with melatonin (MLT) to overcome CCl4-induced liver fibrosis and also investigate the individual impact of melatonin and MSCs against CCl4-induced liver impairment in animal model. Female BALB/c mice were used as CCL4-induced liver fibrotic animal model. Five groups of animal model were made; negative control, Positive control, CCl4+MSCs treated group, CCl4+MLT treated group and CCl4+MSCs+MLT treated group. Cultured MSCs from mice bone marrow were transplanted to CCl4-induced liver injured mice model, individually as well as together with melatonin. Two weeks after MSCs and MLT administration, all groups of mice were sacrificed for examination. Morphological and Histopathological results showed that combined therapy of MSCs+MLT showed substantial beneficial impact on CCl4-induced liver injured model, compared with MSCs and MLT individually. Biochemically, considerable reduction was observed in serum bilirubin and ALT levels of MLT+MSC treated mice, compared to other groups. PCR results shown down-regulation of Bax and up-regulation of Bcl-xl and Albumin, confirm a significant therapeutic effect of MSCs+MLT on CCI4-induced liver fibrosis. From the results, it is concluded that combined therapy of MSCs and MLT show strong therapeutic effect on CCL4-induced liver fibrosis, compared with MSCs and MLT individually.

Resumo A fibrose hepática é a fase inicial de qualquer doença hepática crônica, e em sua fase final desenvolve-se para cirrose. As doenças hepáticas crônicas são uma questão de saúde global crucial e a causa de aproximadamente 2 milhões de mortes por ano em todo o mundo. A cirrose, hoje em dia, é a 11ª causa mais comum de morte globalmente. O tratamento da célula-tronco mesenquimal (MSCs) é uma maneira eletiva de tratar a doença hepática aguda e crônica. O objetivo deste estudo é melhorar o potencial terapêutico dos MSCs combinados com a melatonina (MLT) para superar a fibrose hepática induzida por CCl4 e também investigar o impacto individual da melatonina e MSCs contra o comprometimento do fígado induzido por CCl4 no modelo animal. Os ratos BALB / C fêmeas foram usados como modelo de animal fibrótico de fígado induzido por CCl4. Cinco grupos de modelo animal foram feitos: Controle Negativo, Controle Positivo, CCl4 + MSCs Tratados Grupo, Grupo Tratado CCl4 + MLT e Grupo Tratado CCl4 + MSCs + MLT. MSCs cultivados da medula óssea dos ratos foram transplantados para o modelo de camundongos de fígado induzido por CCl4, individualmente, bem como em conjunto com a melatonina. Duas semanas após a administração MSCs e MLT, todos os grupos de camundongos foram sacrificados para o exame. Os resultados morfológicos e histopatológicos mostraram que a terapia combinada do MSCs + MLT mostrou impacto benéfico substancial no modelo ferido no fígado induzido pelo CCl4, em comparação com o MSCs e o MLT individualmente. A redução bioquimicamente considerável foi observada em bilirrubina sérica e níveis ALT de ratinhos tratados com MLT + MSCs, em comparação com outros grupos. Os resultados de PCR mostraram regulação negativa do BAX e regulação positiva do BCL-XL e da albumina, confirmando um efeito terapêutico significativo do MSCs + MLT na fibrose hepática induzida por CCl4. Dos resultados, conclui-se que a terapia combinada de MSCs e MLT mostram um forte efeito terapêutico na fibrose hepática induzida por CCl4, em comparação com MSCs e MLT individualmente.

Genomic characterization of Puccinia triticina using molecular marker technology / Caracterização genômica de Puccinia triticina usando tecnologia de marcadores moleculares

Leaf rust, caused by Puccinia triticina, is the most common rust disease of wheat. The fungus is an obligate parasite capable of producing infectious urediniospores. To study the genetic structure of the leaf rust population 20 RAPD primers were evaluated on 15 isolates samples collected in Pakistan. A total of 105 RAPD fragments were amplified with an average of 7 fragments per primer. The number of amplified fragments varied from 1 to 12. GL Decamer L-07 and GL Decamer L-01 amplified the highest number of bands (twelve) and primer GL Decamer A-03 amplified the lowest number of bands i.e one. Results showed that almost all investigated isolates were genetically different that confirms high genetic diversity within the leaf rust population. Rust spores can follow the migration pattern in short and long distances to neighbor areas. Results indicated that the greatest variability was revealed by 74.9% of genetic differentiation within leaf rust populations. These results suggested that each population was not completely identical and high gene flow has occurred among the leaf rust population of different areas. The highest differentiation and genetic distance among the Pakistani leaf rust populations were detected between the leaf rust population in NARC isolate (NARC-4) and AARI-11and the highest similarity was observed between NARC isolates (NARC-4) and (NARC-5). The present study showed the leaf rust population in Pakistan is highly dynamic and variable.

A ferrugem da folha, causada por Puccinia triticina, é a ferrugem mais comum do trigo. O fungo é um parasita obrigatório, capaz de produzir urediniósporos infecciosos. Para estudar a estrutura genética da população de ferrugem da folha, 20 primers RAPD foram avaliados em 15 amostras de isolados coletadas no Paquistão. Um total de 105 fragmentos RAPD foram amplificados com uma média de 7 fragmentos por primer. O número de fragmentos amplificados variou de 1 a 12. GL Decamer L-07 e GL Decamer L-01 amplificaram o maior número de bandas (doze), e o primer GL Decamer A-03 amplificou o menor número de bandas, ou seja, um. Os resultados mostraram que quase todos os isolados investigados eram geneticamente diferentes, o que confirma a alta diversidade genética na população de ferrugem da folha. Os esporos de ferrugem podem seguir o padrão de migração em distâncias curtas e longas para áreas vizinhas. Os resultados indicaram que a maior variabilidade foi revelada por 74,9% da diferenciação genética nas populações de ferrugem. Esses resultados sugeriram que cada população não era completamente idêntica e um alto fluxo gênico ocorreu entre a população de ferrugem da folha de diferentes áreas. A maior diferenciação e distância genética entre as populações de ferrugem da folha do Paquistão foram detectadas entre a população de ferrugem da folha no isolado NARC (NARC-4) e AARI-11 e a maior similaridade foi observada entre os isolados NARC (NARC-4) e (NARC-5). O presente estudo mostrou que a população de ferrugem da folha no Paquistão é altamente dinâmica e variável.

Effectiveness of soft tissue augmentation using subepithelial connective tissue graft in comparison with free gingival graft and no graft for increasing the width of keratinized mucosa around dental implants: a meta-analysis

The soft tissues around dental implants are important to prevent inflammatory peri-implant diseases and ensure the long-term survival of a dental implant. Periodontal plastic surgery has evolved from traditional mucogingival surgery, according to Zuhr et al as a result of the development of subepithelial connective tissue grafts/free gingival grafts. So, the aim of this review was to compare the effectiveness of soft tissue augmentation using subepithelial connective tissue graft in comparison with free gingival graft and no graft for increasing the width of keratinized mucosa around dental implants. The review was according to PRISMA protocol. A comprehensive search of the specialized databases was performed to include the studies. Quality assessment and meta-analysis were carried out. 10 articles included. Two articles evaluated KTW with FGG and SCTG; FGG and no graft (3); SCTG and no graft (5). All the included studies assessed either primary or secondary outcome measures. In the end, it was concluded that for soft tissue volume augmentation, SCTG is a treatment choice for an increase in KTW at implant sites.

Diseases and Pests Harmful to Honeybees (Apis spp.) and Their Management Tactics: A Review

Honeybees (Apis spp.) play a vital role in pollination and contribute significantly to global agriculture. However, the health and survival of honeybee colonies are threatened by a range of harmful insect pests and diseases. This review provides an overview of the major pests and diseases that impact honeybee colonies and explores the diverse management tactics employed to mitigate their effects. The primary focus is on key pests such as the Varroa mite (Varroa destructor), which inflicts considerable damage by parasitizing adult bees and their brood, facilitating the transmission of debilitating viruses. Management strategies for Varroa mites encompass chemical treatments, integrated pest management (IPM) approaches, and organic treatments to curtail mite populations and prevent colony collapse. Another significant threat discussed is the small hive beetle (Aethina tumida), a beetle species that disrupts hives by laying eggs in comb and consuming stored resources. Hive manipulation, traps, and chemical controls are among the tactics utilized to control small hive beetle populations and mitigate their impact. The review also addresses wax moths (Galleria mellonella and Achroia grisella), which target hive comb, potentially causing comb destruction and honey fermentation. Hive maintenance, freezing, and pheromone traps are outlined as effective strategies to combat wax moth infestations. Additionally, the review covers Nosema infections (Nosema apis and Nosema ceranae), and microsporidian parasites that compromise adult bee health by weakening immune systems and reducing foraging efficiency. Hive hygiene, medications, and genetic selection are explored as methods to manage Nosema infections and bolster colony resilience. To effectively manage these harmful pests and diseases, a holistic and integrated approach is recommended. Beekeepers are encouraged to remain informed about the latest research findings and implement appropriate measures, considering local conditions and sustainable beekeeping practices. By combining scientific knowledge with practical application, the resilience of honeybee colonies can be enhanced, ensuring the vital role they play in pollination and global food security.

Dosimetric comparison of rectal carcinoma radiation therapy using three dimensional conformal radiation therapy and intensity modulated radiation therapy: an analytical observational study

Rectal cancer is the second most common cancer in large intestine. Recently, preoperative chemoradiotherapy has been generally used in the management of locally advanced rectal cancer on the basis of several benefits proven by clinical studies, in the aspect of better locoregional tumor control, reduced toxicity of normal organs, and an increased chance of preserving the anal sphincter, when compared with postoperative chemoradiotherapy. In this observational study, conducted between January 2017 and December 2021, pursuant to the recommendations of the radiation therapy oncology group (RTOG), all patients underwent CT simulation, a bladder protocol and target contouring. 10 patients were treated with intensity modulated radiotherapy (IMRT) and 10 with three-dimensional conformal radiation therapy (3DCRT). Planned target volume (PTV) coverage, homogeneity index (HI), conformity index (CI), and doses to organs at risk (OAR) were compared. Our findings showed that 3DCRT and IMRT have statistically significant differences in PTV coverage and dosages to OAR (p<0.001), proving that IMRT achieves improved target dose coverage and superior normal tissue avoidance (bladder and intestine) compared to 3DCRT.

Background: Dental implants are now regarded as an effective treatment option for replacing missing teeth. The objective was to evaluate the socket shield approach with immediate temporization to the conventional instantaneous implant with immediate temporization utilizing the parameters of horizontal and vertical dimensional bone loss, crestal bone thickness (CBT) and pink esthetic score (PES). Methods: This prospective study was carried out at Banasree Dental and German Dental implant surgery centers from December 2010 to December 2020 where 74 patients who had non-restorable maxillary teeth in the esthetic region were conducted and evaluated for implant settlement. The allocated individuals were divided into two groups immediate implant with socket shield group (study group, n=22) and the conventional immediate implant placement group (control group, n=52). SPSS version 21.0 was used to analyze all of the data. Results: Mean value of crestal bone thickness (CBT) at the pre-operative time was 1.31±0.2 in both groups but at the 6 months follow-up time it was 1.2±0.22 and 1.07±0.21, at the 24 months follow-up time it was 1.13±0.24 and 0.99±0.20 and at the 60 months follow-up time in was 1.05±0.27 and 0.79±0.15 and at the 120 months follow-up time it was 1.03±0.29 and 0.69±0.17 in the study and control group respectively. In the study group, the mean value of pink esthetic score was 11.45±1.6 at 6 months follow-up time, 12±0.89 at 24 months, 12.5±0.87 at the 60 months and 12.5±0.86 at the 120 months follow-up time whereas in the control group, it was 11±1.32, 10±1.52, 8.9±1.63 and 7.5±1.55, respectively. Conclusions: The SST group revealed minimal reduction in CBT, horizontal and vertical bone loss and a superior PES compared to conventional immediate implant.

A comparison of the quality of images of chest X-ray between handheld portable digital X-ray & routinely used digital X-ray machine

Background & objectives: Chest X-ray (CXR) is an important screening tool for pulmonary tuberculosis (TB). Accessibility to CXR facilities in difficult-to-reach and underserved populations is a challenge. This can potentially be overcome by deploying digital X-ray machines that are portable. However, these portable X-ray machines need to be validated before their deployment in the field. Here, we compare the image quality of CXR taken by a newly developed handheld X-ray machine with routinely used reference digital X-ray machine through the conduct of a feasibility study. Methods: A total of 100 participants with suspected pulmonary TB were recruited from the outpatient departments of a medical college and a community health centre in Agra. Each participant underwent CXR twice, once with each machine. Both sets of de-identified images were independently read by two radiologists, who were blinded to the type of X-ray machine used. The primary outcome was agreement between image qualities produced by these two machines. Results: The intra-observer (radiologist) agreements regarding the status of the 15 CXR parameters ranged between 74 per cent and 100 per cent, with an unweighted mean of 87.2 per cent (95% confidence interval: 71.5-100). The median Cohen’s kappa values for intra-observer agreement were 0.62 and 0.67 for radiologists 1 and 2, respectively. In addition, on comparison of the overall median score of quality of the image, the handheld machine images had a higher score for image quality. Interpretation & conclusions: The current study shows that a handheld X-ray machine, which is easy to use and can potentially be carried to any area, produces X-ray images with quality that is comparable to digital X-ray machines routinely used in health facilities.

A Case of Refractory Supraventricular Tachycardia in a Newborn

Supraventricular Tachycardia (SVT) is the most common neonatal dysrhythmia with the incidence being 1 in 100 for children of all ages and 1 in 250 for neonates.The origin of supraventricular tachycardia is either above the bifurcation of the bundle of His or it has mechanisms dependent on the bundle of His. Newborns may present with irritability, poor feeding and tachypnea.The most important clinical sign of SVT is tachycardia sometimes associated with hypotension,heart failure,pallor,or decreased level of consciousness.Diagnosis is done with heart rate continuously remaining ? 220 beats per minute with a QRS < 0.08 seconds.Adenosine is the first-line abortive therapy of choice. Intractable SVTs are treated with amiodarone, esmolol,and procainamide. SVT with Circulatory collapse needs a synchronized DC cardio version.Prognosis of SVT is generally excellent in the absence of structural heart disease.

Range of factors in the reduction of hyperhydricity associated with in vitro shoots of Salvia santolinifolia Bioss / Gama de fatores na redução da hiperidricidade associada a brotos in vitro de Salvia santolinifolia Bioss

Abstract Hyperhydricity is a serious physiological disorder and affects In vitro propagation of many plants and as well of Salvia santolinifolia. The donor material to initiate the in vitro culture was the callus taken from the in vitro shoots produced on Murashig and Skoogs (MS) medium at 4.0 mg/l BA. This callus formed numerous hyperhydric shoots on culturing upon the medium of the same composition. The aim was to systematically evaluate the effect of cytokinins (Benzyladnine (BA) and N6-(-2-isopentenyl) adenine (2iP), culture vessels magnitude, medium solidification, source of nitrogen and calcium chloride for the alleviation of hyperhydricity. In the tissue cultures of S. santolinifolia BA and 2iP induced severe hyperhydricity, when other factors i.e. culture vessels magnitude and a suitable concentration of agar, ammonium nitrate (NH4NO3), potassium nitrate (KNO3) & calcium chloride (CaCl2.2H2O) were not optimized. After 30 days' culture, we observed 83.82% hyperhydric shoots at increased level (1.5 mg/l 2iP) and 81.59% at decreased levels (1.0 mg/l 2iP). On the other hand, hyperhydricity percentage at decreased (0.4%) and at increased (0.8%) levels of agar were 72.37% and 39.08%, respectively. MS medium modification with NH4NO3 (412 mg/l), KNO3 (475 mg/l) and CaCl2.2H2O (880 mg/l) was found the best medium to reduced hyperhydricity (23.6%).

Resumo A hiperidricidade é um distúrbio fisiológico sério e afeta a propagação in vitro de muitas plantas e também da Salvia santolinifolia. O material doador para iniciar a cultura in vitro foi o calo retirado dos brotos in vitro produzidos em meio Murashig e Skoogs (MS) a 4,0 mg / l BA. Esse calo formou numerosos rebentos hiperídricos em cultura no meio da mesma composição. O objetivo foi avaliar sistematicamente o efeito das citocininas (Benziladnina (BA) e N6 - (- 2-isopentenil) adenina (2iP), magnitude dos vasos de cultura, solidificação do meio, fonte de nitrogênio e cloreto de cálcio para o alívio da hiperidricidade. culturas de tecidos de S. santolinifolia BA e 2iP induziram hiperidricidade severa, quando outros fatores, como magnitude dos vasos de cultura e uma concentração adequada de ágar, nitrato de amônio (NH4NO3), nitrato de potássio (KNO3) e cloreto de cálcio (CaCl2.2H2O), não foram otimizados. Após 30 dias de cultura, observamos 83,82% de brotos hiperídricos em níveis aumentados (1,5 mg / l 2iP) e 81,59% em níveis reduzidos (1,0 mg / l 2iP). Por outro lado, a porcentagem de hiperidricidade diminuiu (0,4%) e em níveis aumentados (0,8%) de ágar foram 72,37% e 39,08%, respectivamente. A modificação do meio MS com NH4NO3 (412 mg / l), KNO3 (475 mg / l) e CaCl2.2H2O (880 mg / l) foi encontrada melhor hiperidricidade média a reduzida (23,6%).

Review on trypanosomiasis and their prevalence in some country on the Red Sea / Avaliação da tripanossomíase e sua prevalência em alguns países do mar Vermelho

Abstract Trypanosomiasis is a protozoan infection affecting both human and animals in almost all parts of the world. It can affect a very large range of domestic and wild hosts including camelids, equines, cattle, buffaloes, sheep, goats, pigs, dogs and other carnivores, deer, gazelles and elephants. This review paper was designed to address the effect of this economically important disease in countries on the Red Sea, especially in Egypt, Sudan, Somalia, and Saudi Arabia during the period 2010 to 2020. The prevalence of trypanosomiasis is different between these countries due to different types of diagnostic methods (Giemsa-stained blood smears, Hematocrit centrifugation, Serological test, and molecular analysis PCR) used and differential distribution of vector (Tse tse) flies. In current review, retrospective studies of published literature on distribution and prevalence of Trypanosoma evansi infection in the Red Sea Countries was conducted [Google Scholar and PubMed were used to retrieve the published literature from 2000-2020. A total of 77 published articles met the eligibility criteria and were reviewed. A total of 16 reports have been reported on the prevalence and distribution of Trypnosoma evansi infection in the Red Sea Countries have been from 2010-2020]. According to the published literature, we can say that trypanosomiasis in camels are more prevalent in Sudan than in other countries, followed by 17% and 51.78% in both clinical and non-clinical cases. Hence, the reliable diagnostic tests should be used for rapid treatment or control of the disease as if not treated appropriately in early-stage, can lead to death of the camels.

Resumo A tripanossomíase é uma infecção por protozoário que afeta humanos e animais em quase todas as partes do mundo. Pode afetar grande variedade de hospedeiros domésticos e selvagens, incluindo camelídeos, equinos, gado, búfalos, ovelhas, cabras, porcos, cães e outros carnívoros, veados, gazelas e elefantes. Este artigo de revisão foi elaborado para abordar o efeito dessa doença economicamente importante em países do mar Vermelho, especialmente Egito, Sudão, Somália e Arábia Saudita, durante o período de 2010 a 2020. A prevalência de tripanossomíase é diferente entre esses países devido a tipos distintos de métodos diagnósticos (esfregaços de sangue corados com Giemsa, centrifugação de hematócrito, teste sorológico e PCR de análise molecular) usados ​​e distribuição diferencial de moscas vetoras (tsé-tsé). Na revisão atual, foram realizados estudos retrospectivos da literatura publicada sobre distribuição e prevalência da infecção por Trypanosoma evansi nos países do mar Vermelho [Google Scholar e PubMed foram usados ​​para recuperar a literatura publicada de 2000 a 2020. Um total de 77 artigos publicados preencheu os critérios de elegibilidade e foi revisado. E há também 16 relatos sobre a prevalência e distribuição da infecção por Trypnosoma evansi nos países do mar Vermelho, de 2010 a 2020]. De acordo com a literatura publicada, podemos afirmar que a tripanossomíase em camelos é mais prevalente no Sudão do que em outros países, seguida por 17% e 51,78% em casos clínicos e não clínicos. Assim, os testes diagnósticos confiáveis ​​devem ser utilizados para o tratamento rápido ou controle da doença, pois, se eles não forem tratados de forma adequada na fase inicial, isso pode levar à morte dos camelos.

Death caused by covid-19 in top ten countries in Asia affected by covid-19 pandemic with special reference to Pakistan / Morte causada por covid-19 nos dez principais países da Ásia afetados pela pandemia de covid-19, com referência especial ao Paquistão

Abstract The COVID-19 is a contagious viral disease, was first emerged in Wuhan, China in December 2019 and became the whole world on alert. The mortality rate in top most countries in Asia with special reference to Pakistan has been focused. Since February 26 to September 2020 the total confirmed cases and mortality rate was measured through Wikipedia and the notable journals. Iran is the only country having highest number of deaths (5.73%) followed by Indonesia (3.77%) while Saudi Arabia shows the lowest number of deaths as 1.39%. In Pakistan the first case was confirmed in 26th February, 2020. The nCov-19 has closely related to severe acute respiratory syndrome (SARS) hence SARS COV-2 was named. This virus is responsible for more than 33.9 million deaths in over all the world as of 20th September, 2020. The number of new cases is increasing time to time. Sindh province of Pakistan has reported the highest number of cases till September, 20, 2020 as compared to other parts of the country and has the highest number of death followed by Khyber Pakhtunkhwa. Because of the person to person contact the disease is spreading rapidly. The individuals who has already infected with other diseases like cancer or diabetic etc. are vulnerable. The nCOV-19 is the most contagious due to its mode of transmission. There is still no vaccine is available for the treatment of disease caused by nCoV-2019. It is therefore the only option to control this pandemic is to adopt effective preventive measures.

Resumo A covid-19 é uma doença viral contagiosa, que surgiu pela primeira vez em Wuhan, China, em dezembro de 2019, e deixou o mundo todo em alerta. A taxa de mortalidade na maioria dos principais países da Ásia, com referência especial ao Paquistão, foi enfocada. De 26 de fevereiro a setembro de 2020, o total de casos confirmados e a taxa de mortalidade foram medidos por meio da Wikipedia e de periódicos notáveis. O Irã é o único país com maior número de mortes (5,73%), seguido pela Indonésia (3,77%), enquanto a Arábia Saudita mostra o menor número de mortes, 1,39%. No Paquistão, o primeiro caso foi confirmado em 26 de fevereiro de 2020. O nCov-19 está intimamente relacionado à síndrome respiratória aguda grave (SARS), daí o nome SARS COV-2. Esse vírus é responsável por mais de 33,9 milhões de mortes em todo o mundo em 20 de setembro de 2020. O número de novos casos está aumentando de tempos em tempos. A província de Sindh, no Paquistão, registrou o maior número de casos até 20 de setembro de 2020, em comparação com outras partes do país, e tem o maior número de mortes, seguida por Khyber Pakhtunkhwa. Por causa do contato pessoa a pessoa, a doença está se espalhando rapidamente. Indivíduos que já foram diagnosticados com outras doenças, como câncer ou diabetes, etc. são mais vulneráveis. O nCOV-19 é o mais contagioso devido ao seu modo de transmissão. Ainda não há vacina disponível para o tratamento da doença causada pelo nCoV-2019. Portanto, a única opção para controlar essa pandemia é a adoção de medidas preventivas eficazes.
