Present research work represents antiviral and antibacterial value of body fat of Saara hardwickii commonly called as spiny tailed lizard. Oil was extracted from body fats located in the ventral region of this animal using hydrocarbons e.g., n-hexane, methanol, butanol and ethyl acetate as a solvent. The antibacterial activity of lizard oil was tested against standard as well as multi-resistant lines ofEscherichia coli, Styphalococcus aureus, Pseudomonas aeruginosa and Proteus vulgaris alone and with antibiotic ampicillin. For antibacterial potential, Ethyl acetate and Butanol solvent extract showed best zone of inhibition (7mm) with P. aeruginosa and S. aureus respectively. For antiviral potential, Butanol and Methanol extract showed best HA (Hemagglutination) titer of 04 with NDV and IBV viral strain respectively. It is concluded that lizard oil has antimicrobial potential against different pathogens strains (virus, bacteria).

O presente trabalho de pesquisa apresenta a importância antiviral e antibacteriana da gordura corporal de Saara hardwickii, comumente chamado de lagarto de cauda espinhosa. O óleo foi extraído de gorduras corporais localizadas na região ventral desse animal usando hidrocarbonetos, por exemplo, n-hexano, metanol, butanol e acetato de etila, como solvente. A atividade antibacteriana do óleo do lagarto foi testada em linhagens padrão e multirresistentes de Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa e Proteus vulgaris, de forma isolada e com antibiótico ampicilina. Para o potencial antibacteriano, acetato de etila e extrato de butanol apresentaram melhor zona de inibição (7 mm) com P. aeruginosa e S. aureus, respectivamente. Para o potencial antiviral, o extrato de butanol e o extrato de metanol apresentaram melhor título de hemaglutinação de 4 com as cepas virais NDV e IBV, respectivamente. Conclui-se que o óleo do lagarto possui potencial antimicrobiano contra diferentes cepas de patógenos (vírus e bactérias).

Biodiversity of commercially important finfish species caught by mid-water and bottom trawls from two different coasts of Arabian Sea: Threats and conservation strategies / Biodiversidade de espécies de peixes comercialmente importantes capturadas por redes de arrasto de médio e fundo do Baluchistão e costas de Sindh do mar da Arábia no Paquistão: Ameaças e estratégias de conservação

Abstract This study was conducted to estimate the diversity and the occurrence of commercially important finfish species collected by twenty fish sampling site of Sindh and Baluchistan coasts of the Arabian Sea in Pakistan from January to December 2019. Additionally, physicochemical characteristics of seawater were analyzed from these selected sites and found to be within suitable ranges required for fish growth and survive. A total of 81287 fish individuals were collected and identified as 49 species belonging to 26 families in our study. The most diversified family was Sparidae (13 species) followed by Carangidae and Lutjanidae (4 species), Mullidae, Serranidae, Ariidae (3 species), and Sciaenidae (2 species). The remaining 20 families were represented by only one species. The values of Shannon diversity index calculated for the four selected habitats revealed that high fish diversity was reported at Sonmiani Coast (H'=1.81), while less at Ormara Coast (H'=0.23). Likewise, Evenness index (E) was high at Sonmiani Coast (E=0.50) and less fish diversity was reported at Ormara Coast (E=0.06). Reducing risks to threatened marine species in coastal habitats also requires conservation actions at multiple scales. Thus, it was concluded that our study could be valuable in providing the more information's regarding to the diversity of finfish species and their occurrence along the Pakistan Coast. Further, to better understand the effects, regular monitoring and conservation measures should be taken to mitigate the influence of anthropogenic activities and protect finfish diversity from further decline

Resumo Este estudo foi conduzido para estimar a diversidade e a ocorrência de espécies de peixes comercialmente importantes coletadas por vinte locais de amostragem de peixes nas costas de Sindh e Baluchistão do mar da Arábia, no Paquistão, de janeiro a dezembro de 2019. Além disso, as características físico-químicas da água do mar foram analisadas a partir desses peixes locais selecionados e considerados dentro dos intervalos adequados necessários para o crescimento e sobrevivência dos peixes. Um total de 8.1287 indivíduos de peixes foi coletado e identificado como 49 espécies pertencentes a 26 famílias em nosso estudo. A família mais diversificada foi Sparidae (13 espécies), seguida por Carangidae e Lutjanidae (4 espécies), Mullidae, Serranidae, Ariidae (3 espécies) e Sciaenidae (2 espécies). As 20 famílias restantes foram representadas por apenas uma espécie. Os valores do índice de diversidade de Shannon calculados para os quatro habitats selecionados revelaram que uma alta diversidade de peixes foi relatada na costa Sonmiani (H' = 1,81), enquanto menos na costa Ormara (H' = 0,23). Da mesma forma, o índice de regularidade (E) foi alto na costa de Sonmiani (E = 0,50) e menos diversidade de peixes foi relatada na costa de Ormara (E = 0,06). A redução dos riscos para as espécies marinhas ameaçadas em habitats costeiros também requer ações de conservação em várias escalas. Assim, concluiu-se que nosso estudo pode ser valioso para fornecer mais informações sobre a diversidade de espécies de peixes finos e sua ocorrência ao longo da costa do Paquistão. Além disso, para compreender melhor os efeitos, medidas regulares de monitoramento e conservação devem ser tomadas para mitigar a influência das atividades antropogênicas e proteger a diversidade de peixes finos de um declínio maior.

Complications after Stapled Hemorrhoidectomy: A Single Center Experience

Background: A circumferential strip of mucosa about 1.5 to 2 centimetres above the dentate line is removed in stapled hemorrhoidectomy, a new technique for haemorrhoids treatments. Objective: The aim of the study was to evaluate complications after stapled hemorrhoidectomy.Methods:A total of 101 patients between the age group 20 to 70 years were diagnosed with grade 3 and grade 4 haemorrhoids. Patients are included in stapled haemorrhoidectomy. The questionnaire focused on stapled hemorrhoidectomy procedures performed in the period July 2018 to June 2020. Descriptive analysis was done based on the student抯 T-test using SPSS 24 software version. The level of significance was set at 5% (p < 0.05).Results:In the 2-years timeframe, out of 101 patients in the Immediate (within 1 week) complications of stapled hemorrhoidectomy, 84.16% were in None, 5.94% were severe pain, 3.96% were bleeding, 1.98% were Thrombosis, 0.99% were urinary retention, 1.98% were Anastomotic dehiscence 0.99% were Fissure, 0.99% were perineal intramural hematoma and 0.99% were submucosal abscess. Out of 90.09% were in none, 1.98% were Recurrent hemorrhoids, 0.99% were Severe pain, Stenosis, Fissure, Skin tag, Thrombosis, Staples problems, Intramural abscess and Intussusception.Conclusion:Although stapled hemorrhoidectomy appears to be promising, we believe that a multicenter randomized controlled trial with a long-term follow-up comparing stapled hemorrhoidectomy and banding is required before the treatment can be recommended. The majority of difficulties can be avoided by following the rectal wall anatomy during the surgery.

Exogenous application of bio-stimulant and growth retardant improved the productivity of cotton cultivars under different planting arrangement / A aplicação exógena de bioestimulante e regulador de crescimento na melhoria da produtividade de cultivares de algodão sob diferentes configurações de plantio

Optimum planting arrangement is an important attribute for efficient utilization of available resources and to obtain high yield of cotton. Application of plant growth promoter and retardant on cotton in improved planting density are the innovative techniques in the establishment of more productive cotton crop. Therefore, we planned a field study to assess the role of bio-stimulant and growth retardant in the resource utilization efficiency of cotton cultivars planted under variable row spacing at Agronomic Research Area Bahauddin Zakariya University and Usmania Agricultural Farm Shujabad during Kharif 2012. Experimental treatments consisted of cotton genotypes viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and ultra-narrow row spacing (25 cm) with foliar spray of bio-stimulant (moringa leaf extract) and growth retardant (mepiquate chloride), either sole or in combination, keeping distilled water as a control. Exogenously applied MLE alone and MLE + MC significantly enhanced the number of squares, flowers and green bolls per plant leading to higher cotton seed and lint yield of CIM 598 cultivar cultivated under conventional row spacing. While application of MC alone and MLE + MC produced maximum micronaire value, fiber strength and fiber uniformity ratio of CIM 573 cultivar cultivated under conventional row spacing. The results suggested that application of MLE is a possible approach to enhance the cotton productivity and the use of MC to enhance the fiber quality attributes under conventional row spacing.

A configuração ideal de plantio é um atributo importante para a utilização eficiente dos recursos disponíveis e para obter alto rendimento de algodão. A aplicação de promotores de crescimento de plantas e reguladores de crescimento no algodão em uma densidade de plantio adequada são técnicas inovadoras na obtenção de safras de algodão mais produtivas. Portanto, foi planejado um estudo de campo para avaliar o papel de um bioestimulante e um regulador de crescimento na eficiência da utilização de recursos de cultivares de algodão plantadas com espaçamento variável entre linhas na Área de Pesquisa Agronômica Universidade Bahauddin Zakariya e Usmania Agricultural Farm Shujabad durante Kharif 2012. Os tratamentos experimentais consistiram em genótipos de algodão viz. CIM-573 e CIM-598, cultivadas sob espaçamento convencional (75 cm), médio (50 cm) e ultraestreito (25 cm) e pulverização foliar de bioestimulante (extrato de folha de moringa) e regulador de crescimento (cloreto de mepiquato)), sozinho ou combinado, mantendo a água destilada como controle. O MLE aplicado exogenamente sozinho e o MLE + MC aumentaram significativamente o número de quadrados, flores e cápsulas verdes por planta, levando a um maior rendimento de sementes e fibra de algodão da cultivar CIM 598 cultivada sob espaçamento convencional entre fileiras. Enquanto a aplicação de MC sozinho e MLE + MC produziu valor máximo de micronaire, resistência da fibra e razão de uniformidade da fibra da cultivar CIM 573 cultivada sob espaçamento convencional entre linhas. Os resultados sugeriram que a aplicação do MLE é uma abordagem possível para aumentar a produtividade do algodão e o uso de MC para aprimorar os atributos de qualidade da fibra no espaçamento convencional entre linhas.

Detection of human Sarcocystosis using dried blood on filter papers: An Immunofluorescent Antibody Test

@#Sarcocystosis, a parasitic infection caused by a protozoa belonging to the genus Sarcocystis, is found worldwide in both and animals. Sarcocystis spp., require two animal hosts to complete their life cycle. The infection has gathered more global attention after recent outbreaks, especially amongst wester travellers to Malaysia. Other than sporadic cases and the current outbreaks, little information is available regarding human Sarcocystis infection in Malaysia. The present study aims to determine the prevalence of sarcocystosis among humans using an immunofluorescent antibody (IFA) test applied to dried blood on filter papers. A total of 200 blood samples were collected on filter papers from autopsy cases at two Malaysian hospitals: Sungai Buloh Hospital (peninsular Malaysia) and Queen Elizabeth Hospital (Malaysian Borneo). Antigens were prepared from bradyzoites harvested from positive goats’ muscle samples. Of the 200 samples, 32 (16%) had Sarcocystis antibodies that showed positive fluorescence reactions on filter papers. There was no significant difference (t-test, p value > 0.05) in prevalence rates between samples collected from autopsies at peninsular Malaysia and Malaysian Borneo. The results demonstrated that the filter paper technique can be used as one of the alternative serological tests in the diagnostic of human sarcocystosis.

Comparative Study between the Attenuation of Cardiac Fibrosis by Mesenchymal Stem Cells versus Colchicine.

Introduction: Considered as an end-stage for all cardiovascular diseases, cardiac fibrosis leads to the development of heart failure, thus the ultimate goal is to prevent the progression of fibrosis. Indeed, heart can regenerate itself but to a certain limit based upon the number of resident stem cells which is limited. Thus, stem cells transplantation is considered as a promising therapy. This study aims to examine if MSC transplantation can inhibit the progression of myocardial fibrosis in rat model compared to Colchicine treatment; and if the timing of treatment with MSCs or COL affect the progression of fibrosis. Material & Methods: To induce cardiac fibrosis in 48 female albino rats, Isoproterenol hydrochloride was used. These rats were divided into 2 models: COL-treated group that were treated after 1,2,3 weeks of the last ISO injection by colchicine orally. MSCtreated group that were injected intravenously after 1,2,3 weeks of last ISO injection by MSC. Heart rate and Systolic blood pressure were measured and the levels of Creatine phosphokinase, Lactate dehydrogenase, Matrix Metalloproteinase II and Collagen I were assessed. Moreover, cardiac tissues were examined hitopathologically. Results & Conclusion: MSC were proved to enhance the effect of anti-remodeling of extracellular matrix significantly by modulating the expression of matrix metalloproteinases, which is superior to COL treatment.

Unique roles of nanotechnology in medicine and cancer‑II.

Applications of nanotechnology in medicine and cancer are becoming increasingly popular. Common nanomaterials and devices applicable in cancer medicine are classifiable as liposomes, polymeric‑micelles, dendrimers, nano‑cantilevers, carbon nanotubes, quantum dots, magnetic‑nanoparticles, gold nanoparticles (AuNPs) and certain miscellaneous nanoparticles. Here, we present review of the structure, function and utilities of the various approved, under trial and pretrial nanodevices applicable in the cancer care and medicine. The liposomes are phospholipid‑vesicles made use in carrying drugs to the target site minimizing the bio‑distribution toxicity and a number of such theranostics have been approved for clinical practice. Newly worked out liposomes and polymeric micelles are under the trail phases for nano‑therapeutic utility. A multifunctional dendrimer conjugate with imaging, targeting and drug molecules of paclitaxel has been recently synthesized for cancer theranostic applications. Nano‑cantilever based assays are likely going to replace the conventions methods of chemical pathological investigations. Carbon nanotubes are emerging for utility in regenerative and cancer medicine. Quantum dots hold great promise for the micro‑metastasis and intra‑operative tumor imaging. Important applications of magnetic nanoparticles are in the cardiac stents, photodynamic therapy and liver metastasis imaging. The AuNPs have been employed for cell imaging, computed tomography and cancer therapy. Besides these categories, miscellaneous other nanoparticles are being discovered for utility in the cancer diagnosis and disease management. However, the use of nanoparticles should be cautious since the toxic effects of nanoparticles are not well‑known. The use of nanoparticles in the clinical practice and their toxicity profile require further extensive research.

Recovery of Schistosoma haematobium ovum from Labeo rohita: first report from Pakistan

Schistosomiasis, also known as bilharzia, is a parasitic disease caused by trematodes from the genus Schistosoma that can infect humans and animals. S. mansoni, S. japonicum, and S. mekongi all causes intestinal schistosomiasis except S. haematobium that causes urinary schistosomiasis. It is only specie which effects urinary system, it can affect liver, heart, lungs also but very rarely. Schistosoma haematobium is endemic to over 50 countries in Africa and the Middle East and Western Asia and may be fatal in HIV positive people. A number of reports from the African countries like Nigeria have been reported. A few cases are reported 9but in Pakistan it has never been reported before in native people. It is first time reported in Pakistan in the intestine of Rahu (Labeo rohita). The purpose of this study is to elaborate the approach of zoonotic agent by various other routes including the commonly available fish

Unique roles of nanotechnology in medicine and cancer.

Here we review the scope of nanotechnology in Medicine and human cancer. The imaging and therapy agents can be co‑delivered by same nanoparticle for integrated molecular diagnosis, therapy, and follow‑up of cancer or ‘cancer theranostics’ is implying multimodal use of nanoparticles in cancer care. Nanoparticles are used for passive targeting and in conjugation with ligands for active targeting, to have optimum concentrations of imaging and therapeutic agents in the tumor cells specifically, sparing normal tissue from unwanted side effects. Potential utility of nanoparticles in the nano biosensors, nano fluorescent tag imaging, nano tumor mapping, nano gene profiling, nano molecular delivery, nano chemo‑radio therapy, nano thermotherapy, nano photodynamic therapy, etc., is tending to revolutionize medicine particularly personalized cancer care and laboratory. Nanoparticle induced oxidative stress based inflammation reported by few studies; in lung, liver and brain required further investigations.

High Fibrinogen Level is An Independent Predictor of Presence and Severity of Coronary Artery Disease.

Background: Fibrinogen has been identified as an independent risk factor for cardiovascular disease and associated with traditional cardiovascular risk factors. Few reports have so far investigated the relationship between fibrinogen levels and the extent of coronary artery disease (CAD) as evaluated by coronary angiography. Therefore the current study was carried out to evaluate the relationship between fibrinogen levels and the extent of CAD as evidenced by coronary angiography. Method: A total of 210 patients having ischemic heart disease including chronic stable angina, unstable angina, non-ST elevated myocardial infarction & ST elevated myocardial infarction were evaluated in National Institute of Cardiovascular Disease (NICVD), Dhaka with a view to find out the relationship between fibrinogen levels and the extent of CAD undergoing coronary angiography. Patients were divided in 3 groups according to fibrinogen levels: Group I = fibrinogen levels <400 mg/dl, Group II = fibrinogen levels (400-600) mg/dl, Group III = fibrinogen levels > 600 mg/dl. In this study, angiographic severity was assessed by vessel score, stenosis score and lesion morphology and tries to find out their relationship with angiographic severity and fibrinogen level. Result: Using a prospective analytic design we studied 210 patients who were divided into 3 groups : Vessel score in Group I, Group II & Group III were 1.14 ± 0.56, 2.24 ± 0.58, & 3.00 ± 0.65 respectively which was statistically significant (p < 0.01) and Stenosis score in group- I, group- II & group- III were 6.00 ± 4.19, 18.72 ± 4.94, & 32.41 ± 15.75 respectively which was statistically significant (p < 0.01). Regarding morphology of the lesions, complex lesions in group I, group II & group III were 21%, 32% & 39% respectively (statistically significant; p < 0.01). Conclusion: High fibrinogen level is independently and significantly associated with more severe coronary artery disease. Serum fibrinogen can be used as a new and even simpler tool for risk stratification in acute coronary syndrome.

Bacteriological Spectrum of Different Infections and their Antibiogram at NICVD, Dhaka.

Background: One of the major causes of death in the current era is the infectious diseases. Aerobic bacteria are one of the most commonly isolated organisms from hospitalised patients. Objectives: The aim of the present study was to observe the infections caused by aerobic bacteria and their antibiotics susceptibility pattern. Methods: This retrospective study was carried out in the National Institute of Cardiovascular Diseases (NICVD) from January 2012 to December 2012 for a period of one year. Patients who were admitted in medical wards and medical ICU suffering from different infections were undertaken for this study. Proper thoroughly clinical examination, routine and specific investigations were done in each case. Microbiological samplings were tried on day 1, after completion of antibiotic therapy or in between as required. Aerobic bacterial culture and sensitivity tests were done according to clinical laboratory standard institute (CLSI) standard. Result: A total of 660 samples were studied of which male (70.0%) were predominant than female (30.0%). The highest number of patients was in the age group of 30-60 years (54.0%) followed by 15-30 years (21.5%) and less than 15 years (13.0%). The mean age with standard deviation was 38.61±19.236 years. The most common isolated bacteria was Escherichia coli (40.1%) followed by Pseudomonas species (30.4%), coagulase negative Staphylococcus (19.0%) and coagulase positive Staphylococcus (5.9%); however, beta-haemolytic Streptococcus (4.2%) was detected. Urine culture has yielded Pseudomonas species (13.3%), E. coli (71.1%) and CNS (15.0%). From pus Pseudomonas species (37.3%) was isolated mostly which was 62 cases followed by E. coli (31.3%), CNS (19.3%) and CPS (7.2%). Pseudomonas species was resistant to penicillin, amoxycillin and vancomycin and ~50% resistant to cotrimoxazole, cefuroxim, ceftriaxone, piperacillin, azythromycin, cephalexin, netelmycin and pfloxacillin. Conclusion: In the conclusion, majority bacteria are resistant to commonly used antibiotics.

[ role of laparoscopy in the diagnosis and treatment of undescended testis]

Treatment of the cryptorchid testicle is justified due to the increased risk of infertility and malignancy as well as the risk of testicular trauma and torsion and psychological stigma on patients and their parents. Approximately 20% of cryptorchid testicles are nonpalpable. Many Radiological methods in addition to surgical exploration have been used to localize the non-palpable testis. In these cases, the laparoscopic technique is a usefull method for diagnosis and treatment. Prospective study. From 2005 to 2010, 59 children between 2- 13 years [median age: 4 years] were admitted to our department in Assad and Mwassat hospitals with the diagnosis of nonpalpable testis, 7 of them have bilateral cryptorchidism [66 testicles in total]. Laparoscopy was done for all these patients using 30 degree optic through 5 mm sub umbilical port, 2 additional 5 mm ports were used when necessary as working channels. Direct orchiopexy was done for 10 testicles [15.15%] as laparoscopy indicated that the testicle are located in the inguinal canal, orchiectomy was done for atrophic testis via laparoscopy or inguinal approach in 11 cases [16.16%]. In 14 cases [21.21%] the testicles were absent. In the remaining 31 cases [46.96%] the testicular vessels were clipped [first stage-Stephen Fowler], and orchiopexy was postponed for 6 months. During the second stage all testicles were found viable, except for an atrophied one that we excised, and were brought down freely to the scrotum with a peritoneal patch covering the vas. Laparoscopy is now considered to be the gold standard in the diagnosis and management of nonpalpable ectopic testis. The accuracy of radiological means in locating the nonpalpable testis do not reach 100% except for the selective angiography which is an invasive procedure, while laparoscopy is characterized by the possibility of diagnosis and management at the same time. Compared with the surgical exploration, laparoscopy is preferred in managing nonpalpable testis

New Hope for Resistant Hypertention.

Hypertension is a major public health problem. Despite the increasing awareness of hypertension and its implications among patients and treating physicians, the prevalence of resistant hypertension remains high. Resistant hypertension define as blood pressure that remains elevated above treatment goals despite administration of an optimal three drug regimen that include a diuretic1 The prevalence of resistant hypertension is projected to increase, owing to the aging population and increasing trends in obesity, sleep apnea, and chronic kidney disease. It is estimated that at least 10% of all patients with hypertension are resistant to existing drugs. Management of resistant hypertension must begin with a careful evaluation of the patient to confirm the diagnosis and exclude factors associated with “pseudo-resistance,” such as improper BP measurement technique, the white-coat effect, and poor patient adherence to life-style and/or antihypertensive medications. Despite the use of the appropriate dose and type of diuretic to overcome the management of resistant hypertension, we can’t achieve our goal. But there is at least two devices namely Baroreflex Activation Therapy and Catheter-based renal sympathetic denervation make the new hope for the patient with resistant hypertension.

Relationship between Baseline White Blood Cell count and C-reactive protein with Angiographic severity of Coronary Artery Disease in Patients with Acute Coronary Syndrome.

Inflammation has been shown to play a role in atherosclerosis and acute coronary syndrome. This study was carried out to evaluate the relationship between baseline white blood cell (WBC) count and C-reactive protein (CRP) with angiographic severity of coronary artery disease in patients with acute coronary syndrome and to identify those subsets of patients with acute coronary syndrome who may need to undergo invasive or conservative strategies. Method: A total of 100 patients with acute coronary syndrome including unstable angina, non-ST elevated myocardial infarction & ST elevated myocardial infarction were evaluated in National Institute of Cardiovascular Disease (NICVD), Dhaka with a view to correlate angiographic findings, C-reactive protein and WBC count. Results: This study observed that either raised WBC count or raised CRP independently and combination of both WBC count and CRP elevation were significantly associated with more severe coronary artery disease. Either raised WBC count or raised CRP or combination of raised WBC count and CRP were significant predictor of multivessel disease and high stenosis score. Conclusion: Elevation of WBC count and CRP in patients with acute coronary syndrome are associated with severe coronary disease. WBC count and CRP can be used as a new and even simpler tool for risk stratification in acute coronary syndrome.
