    Collar rot of chili (Capsicum annuum L.) is a very destructive disease caused by a soil-borne fungal pathogen Sclerotium rolfsii Sacc. Generally, chemical fungicides are used to combat the menace but this practice is being discouraged because of health and environmental concerns. In the present study, an alternative environment friendly strategy was used to manage this disease by using farmyard manure (FYM) and two commercial biofertilizers namely Biopower and Feng Shou. S. rolfsii inoculated pot soil was amended with 1% and 2% FYM and the two commercial biofertilizers. Inoculation of soil with S. rolfsii only (positive control) resulted in the highest disease incidence (73%) and plant mortality (60%). Biopower and Feng Shou application reduced disease incidence to 20% and 7%, respectively and plant mortality to 0%. Likewise, 1% and 2% FYM amendment reduced disease incidence to 33% and plant mortality to 26% and 7%, respectively. Under biotic stress of S. rolfsii, FYM and biofertilizers applications, either alone or in combination, significantly enhanced root and shoot growth over positive control. S. rolfsii inoculation significantly increased peroxidase and polyphenol oxidase activities in chili plants which were further increased by application of either of the two biofertilizers. The present study concludes that biofertilizers Biopower and Feng Shou alone or in combination with 2% FYM can be effectively utilized to manage southern blight of chili

    Background: Diabetes mellitus is a common health dilemma worldwide and is characterized by hyperglycemia. Inhibition in the activity of one of the digestive tract enzymes α-glucosidase is one of the therapeutic approaches to hydrolyze carbohydrates into glucose using natural agents. Many natural compounds with α-glucosidase inhibitory activity have transpired to be secondary metabolites. Monotheca buxifolia, native to Pakistan is a major medicinal tree, which has been known for its extensive pharmacological activities.Methods: α-glucosidase activity of ten isolated compounds (lupeol, lupeol acetate, betulin, β-sitosterol, β-amyrin, oleanolic acid, vanillic acid, protocatechuic acid, kaempferol and quercetin) from lipophilic hexane fraction of M. buxifolia (stem and leaves) was assessed against α-glucosidase enzyme using acarbose as a control.Results: All ten compounds hold α-glucosidase inhibition potential (91-99%). However, IC50 (half-maximal inhibitory concentration) values of oleanolic acid (5 µM) were 8-fold lower than that of acarbose. Moreover, inhibition potencies of lupeol (15.87 µM), β-amyrin (18.14 µM) betulin (21.49 µM), quercetin (23.47 µM), and lupeol acetate (29.45 µM) were much stronger than the inhibitory effect obtained from acarbose (38.25 µM).Conclusion: Oleanolic acid of M. buxifolia exhibited a potent inhibitory effect against α-glucosidase, therefore, oleanolic acid may be utilized in medicinal formulations against diabetic disorders.Keywords: Diabetes mellitus; Enzyme inhibition; Medicinal plants; Pentacyclic triterpenes

    Abstract Objective: To compare the factors that lead to early versus late presentation in patients with neck masses Study Design: Group Comparative Study. Study Setting & Duration: Department of Otorhinolaryngology and Head &Neck Surgery at Rawalpindi Teaching Hospital from 01-9-2022 to 01-03-2023. Methods: Approval of the study was obtained from the hospital's ethical committee. A total of 64 patients (32 in each group) were placed in two Groups A &  B. Group A included patients who presented early and Group B included patients who presented late. Both male and female patients were selected. In this study patients suffering from neck masses who have reported for work-up to the Department of ENT, Rawalpindi Teaching Hospital, and fulfil the complete inclusion and exclusion criteria were included. Patients were selected via consecutive nonprobability sampling. The data were analyzed for frequencies by SPSS 24. Results: A total of 64 patients were included in this study. The mean age of these patients was 48.67 ± 9.74 years, ranging from 25 to 70 years. The Frequency distribution of males at 65.63 % was found to be more than that of females at 34.36 %. In the majority of patients, the size of mass more than 1.5 cm (51.56%) revealed malignancy, while only a small percentage of patients (48.44%) had less than 1.5 cm neck mass. The majority of patients (93.75%) with addiction presented late, while just a small number (6.25%) had early presentation. The majority of patients (51.56%) with frequent visits to  Quacks /Hakeem per year were presented late. Regarding socioeconomic status, the majority of patients (28) from upper-class families presented early, compared to (11) patients from middle-class families who presented late, and all (21) patients from lower-class families who presented late. The education level reveals that the majority of patients (31), who were educated, attended a school for more than a year, but only up to ten (matriculate or similar) years, or advanced literacy: got a college- or university-level education, and they displayed early presentation. The 30 uneducated patients, who never attended an educational institution, or attended for less than one year, presented late. 31 patients had frequent visits to health care professionals and were presented early, 30 patients had fewer visits to health care professionals present late with advanced disease.  Conclusion: The majority of patients who were drug and alcohol addicts were presented late with advanced disease. Middle-class families, lower-class families, uneducated patients, and patients who did not see a healthcare provider four or more times per year, make up the majority of visits to Quacks and Hakeem each year and are presented late with advanced disease as compared to the group of patients who belong to upper class, were literate with no history of drug or alcohol addiction and have frequent visits to health care professionals. Both groups were considered to be significant (p=0.00) based on the probability ratio. This study helped to identify the role of various suspected risk factors for late presentation in head and neck cancers in an attempt to reinforce or negate their importance which will help to guide the formation of screening protocols thereby improving morbidity, and mortality and reducing financial costs.

    Background: Sclerotium rolfsii Sacc. is a destructive soil-borne plant pathogen that infects over 500 plant species and causes significant yield losses in many economically important plant species. Synthetic fungicides used to combat the menace also pollute the environment and cause health hazards. In order to search environmental friendly alternatives from natural resources, in the present study, methanolic extracts of three leguminous tree species namely Acacia nilotica (L.) Willd. ex Delile subsp. indica (Benth.) Brenan, Prosopis juliflora (Sw.) DC. and Albizia lebbeck (L.) Benth. were evaluated for their antifungal activity against S. rolfsii. Materials and Methods: Two hundred grams dried leaf material of each of the three test plant species were extracted with methanol for two weeks. After filtration, methanol was evaporated on a rotary evaporator. Malt extract broth was used to make various concentrations of the crude methanolic extracts and their antifungal potential was determined by comparing the fungal biomass in various treatments with control. Chemical composition of methanolic leaf extract of A. nilotica subsp. indica was determined through GC-MS analysis. Results: Methanolic leaf extract of A. nilotica subsp. indica showed the highest fungicidal activity. Fungal biomass was decreased by 17-55% due to various concentrations of this extract over control. Different concentrations of P. juliflora reduced fungal biomass by 3-52%. Fourteen compounds were identified in methanolic extract of A. nilotica subsp. indica. 9,12,15-octadecatrienoic acid, methyl ester, (Z,Z,Z,)- (16.59%) was the most abundant compound followed by 1-pentanol, 2 methyl-, acetate (14.80%); hexanedioic acid, dimethyl ester (13.10%) and cyclotriaconta- 1, 7, 16, 22-tetraone (10.28%). Conclusion: This study concludes that methanolic leaf extract of A. nilotica subsp. indica can be used for management of S. rolfsii

    Objective: To assess knowledge of patients with tuberculosis; about their disease and misconceptions regarding TB. Methods: A cross sectional study was conducted at Out-patient clinics of two teaching hospitals (private and public) in Karachi, Pakistan. A questionnaire was filled for the purpose. Results: A total of 170 patients were interviewed, 112 from private and 58 from a public sector hospital. Cough, fever, bloody sputum and chest pain were recognized as the common symptoms of TB. Eleven (7%) patients thought TB was not an infectious disease and 18 (10.6%) did not consider it a preventable disease. Contaminated food was considered the source of infection by 81 (47.6%) and 96 (57%) considered emotional trauma/stress the causative agent of TB. No counseling about preventing spread was received by 81 (50%) patients and 97 (57%) considered separating dishes as an important means of preventing spread. Thirty one (18%) patients would have discontinued their medications following relief of symptoms. Thirty nine (23%) of the respondents thought that TB could lead to infertility and 66 (38.8%) believed that there were reduced chances of getting married following infection. Conclusion: Misconceptions concerning TB are common in Pakistani patients. Lack of knowledge on Tuberculosis is alarming. (JPMA:56:211;2006

    Schizophyllum commune: An unexploited source for lignocellulose degrading enzymes

    Get PDF
    Lignocellulose represents the most abundant source of carbon in the Earth. Thus, fraction technology of the biomass turns up as an emerging technology for the development of biorefineries. Saccharification and fermentation processes require the formulation of enzymatic cocktails or the development of microorganisms (naturally or genetically modified) with the appropriate toolbox to produce a cost-effective fermentation technology. Therefore, the search for microorganisms capable of developing effective cellulose hydrolysis represents one of the main challenges in this era. Schizophyllum commune is an edible agarical with a great capability to secrete a myriad of hydrolytic enzymes such as xylanases and endoglucanases that are expressed in a high range of substrates. In addition, a large number of protein-coding genes for glycoside hydrolases, oxidoreductases like laccases (Lacs; EC 1.10.3.2), as well as some sequences encoding for lytic polysaccharide monooxygenases (LPMOs) and expansins-like proteins demonstrate the potential of this fungus to be applied in different biotechnological process. In this review, we focus on the enzymatic toolbox of S. commune at the genetic, transcriptomic, and proteomic level, as well as the requirements to be employed for fermentable sugars production in biorefineries. At the end the trend of its use in patent registration is also reviewed.We are thankful to the National Council for Science and Technology (CONACyT) since OETH received a scholarship during the elaboration of this work. We also thank the financial support received from SEP-PRODEP- UAEMOR- PITC- 381. RABG received a postdoctoral fellowship from the Quebec Government

    <p>Abstract</p> <p>Background</p> <p>The incidence of tuberculosis in Pakistan is 181/100,000 population. However, information about transmission and geographical prevalence of <it>Mycobacterium tuberculosis </it>strains and their evolutionary genetics as well as drug resistance remains limited. Our objective was to determine the clonal composition, evolutionary genetics and drug resistance of <it>M. tuberculosis </it>isolates from different regions of the country.</p> <p>Methods</p> <p><it>M. tuberculosis </it>strains isolated (2003–2005) from specimens submitted to the laboratory through collection units nationwide were included. Drug susceptibility was performed and strains were spoligotyped.</p> <p>Results</p> <p>Of 926 <it>M. tuberculosis </it>strains studied, 721(78%) were grouped into 59 "shared types", while 205 (22%) were identified as "Orphan" spoligotypes. Amongst the predominant genotypes 61% were Central Asian strains (CAS ; including CAS1, CAS sub-families and Orphan Pak clusters), 4% East African-Indian (EAI), 3% Beijing, 2% poorly defined TB strains (T), 2% Haarlem and LAM (0.2). Also TbD1 analysis (<it>M. tuberculosis </it>specific deletion 1) confirmed that CAS1 was of "modern" origin while EAI isolates belonged to "ancestral" strain types.</p> <p>Prevalence of CAS1 clade was significantly higher in Punjab (P < 0.01, Pearsons Chi-square test) as compared with Sindh, North West Frontier Province and Balochistan provinces. Forty six percent of isolates were sensitive to five first line antibiotics tested, 45% were Rifampicin resistant, 50% isoniazid resistant. MDR was significantly associated with Beijing strains (P = 0.01, Pearsons Chi-square test) and EAI (P = 0.001, Pearsons Chi-square test), but not with CAS family.</p> <p>Conclusion</p> <p>Our results show variation of prevalent <it>M. tuberculosis </it>strain with greater association of CAS1 with the Punjab province. The fact that the prevalent CAS genotype was not associated with drug resistance is encouraging. It further suggests a more effective treatment and control programme should be successful in reducing the tuberculosis burden in Pakistan.</p
