BackgroundHuman immunodeficiency virus (HIV) is a retrovirus that suppresses the immune system by reducing the CD4+ T lymphocytes level. It has become a global challenge with fast prevalence ratio. Like other developing countries, Pakistan is also struggling for overcoming this viral disease since very first reported case in 1987.AimTo update the society on the alarming rise in HIV cases in Pakistan: challenges and future recommendations at hand.Materials and MethodsThe review paper utilized different search engines such pubmed central, scopus, web of science, google scholar etc. to conduct this review paper.ResultsLack of awareness, low literacy rate, practice of unhygienic equipment in healthcare departments, unstable economy, and unsafe sexual practices are the major factors behind the increasing rate of AIDS in Pakistan.ConclusionBy regulating healthcare practices and policies, promoting psychological counseling to HIV positive patients, educating the society and minimizing commercial sex practices, Pakistan can overcome this viral disease.
Salinity stress is one of the major abiotic factors limiting crop yield in arid and semi-arid regions. Plant growth-promoting fungi can help plants thrive in stressful conditions. In this study, we isolated and characterized 26 halophilic fungi (endophytic, rhizospheric, and soil) from the coastal region of Muscat, Oman, for plant growth-promoting activities. About 16 out of 26 fungi were found to produce IAA, and about 11 isolates (MGRF1, MGRF2, GREF1, GREF2, TQRF4, TQRF5, TQRF5, TQRF6, TQRF7, TQRF8, TQRF2) out of 26 strains were found to significantly improve seed germination and seedling growth of wheat. To evaluate the effect of the above-selected strains on salt tolerance in wheat, we grew wheat seedlings in 150 mM, 300 mM NaCl and SW (100% seawater) treatments and inoculated them with the above strains. Our findings showed that fungal strains MGRF1, MGRF2, GREF2, and TQRF9 alleviate 150 mM salt stress and increase shoot length compared to their respective control plants. However, in 300 mM stressed plants, GREF1 and TQRF9 were observed to improve shoot length. Two strains, GREF2 and TQRF8, also promoted plant growth and reduced salt stress in SW-treated plants. Like shoot length, an analogous pattern was observed in root length, and different salt stressors such as 150 mM, 300 mM, and SW reduced root length by up to 4%, 7.5%, and 19.5%, respectively. Three strains, GREF1, TQRF7, and MGRF1, had higher catalase (CAT) levels, and similar results were observed in polyphenol oxidase (PPO), and GREF1 inoculation dramatically raised the PPO level in 150 mM salt stress. The fungal strains had varying effects, with some, such as GREF1, GREF2, and TQRF9, showing a significant increase in protein content as compared to their respective control plants. Under salinity stress, the expression of DREB2 and DREB6 genes was reduced. However, the WDREB2 gene, on the other hand, was shown to be highly elevated during salt stress conditions, whereas the opposite was observed in inoculated plants.
Modern irrigation practices and industrial pollution can contribute to the simultaneous occurrence of salinity and heavy metal contamination in large areas of the world, resulting in significant negative effects on crop productivity and sustainability. This study aimed to investigate the growth-promoting potentials of an important endophytic fungal strain SL3 and to compare its potential with exogenous IAA (indole-3-acetic acid) in the context of salt and heavy metal stress. The strain was assessed for plant growth-promoting traits such as the production of indole-3-acetic acid, gibberellins (GA), and siderophore. We selected two important crops, mung bean and maize, and examined various physiological and biochemical characteristics under 300 mM NaCl and 2.5 mM Pb stress conditions, with and without the application of IAA and SL3. This study’s results demonstrated that both IAA and SL3 positively impacted the growth and development of plants under normal and stressed conditions. In NaCl and Pb-induced stress conditions, the growth of mung bean and maize plants was significantly reduced. However, the application of IAA and SL3 helped to alleviate stress, leading to a significant increase in shoot/root length and weight compared to IAA and SL3 non-treated plants. The results revealed that photosynthetic pigments, accumulation of catalase (CAT), phenolic contents, polyphenol oxidase, and flavanols are higher in the IAA and SL3-treated plants than in the non-inoculated plants. This study’s findings revealed that applying the SL3 fungal strain positively influenced various physiological and biochemical processes in tested plant species under normal and stress conditions of NaCl and Pb. These findings also suggested that SL3 could be a potential replacement for widely used IAA to promote plant growth by improving photosynthetic efficiency, reducing oxidative stress, and enhancing metabolic activities in plants, including mung and maize. Moreover, this study highlights that SL3 has synergistic effects with IAA in enhancing resilience to salt and heavy stress and offers a promising avenue for future agricultural applications in salt and heavy metal-affected regions.
The purpose of this study is to check out the spread rate of Hepatitis B Virus in the districts of Mardan and Charsadda, KPK Pakistan. As we know that Hepatitis results in damaging liver tissues, so it is one of the serious threats to the human health across the world. Hepatitis can give rise to acute and chronic infection which give rise to Liver cancer or Liver cirrhosis. It may be transfer from one person to another. Its transmission routs are oral, fecal and parental. The purpose of this paper is to check and judge health condition. Blood serum was collected from Mardan Medical Complex, Mardan and District Head Quarter, Charsadda. The paper was design to calculate anti-HBV antibody positive patients with ICT(immune-chromatography technique)based detection among various patients in MMC Mardan and DHQ hospital Charsada and from various regions of Mardan and Charsadda, KPK Pakistan. Total of 10852 patients of HBV in Charsadda and 14168 patients of HBV in Mardan. The blood samples were collected from Oct 2017 to May 2018 from both districts of KPK. The method for testing blood sample was ICT (immune chromatography technique). Our study about 10852 patients in district Charsadda who were at the risk of HBV infection, 103 were screened positive with the prevalence ratio of 0.949%. On the other hand, 14168 patients`s samples were collected in district Mardan, among them 149 were detected positive and ratio of prevalence is 1.051%. According to the above study the ratio of prevalence is lower in Charsadda as compare to Mardan
