Background: The use of medicinal plants to treat various veterinary illnesses has been practiced for millennia in many civilizations. Punjab is home to a diverse ethnic community, the majority of whom work in dairy farming, agriculture, and allied professions and have indigenous practices of treating animal illnesses using native flora. This study was designed to (1) document and preserve information about the applications of medicinal plant species in ethnoveterinary remedies among inhabitants of Punjab, Pakistan, and (2) identify popular plants for disease treatment by quantitative analysis of the obtained data and to assess the pharmacological relevance of these species.

Article Synopsis
  • Enterococcus species, once thought to be harmless, are now recognized as significant causes of healthcare-associated infections due to their virulent genes.
  • A study analyzed 46 Enterococcus strains from urine samples of urinary tract infection patients at a hospital in Bangladesh, aiming to identify these virulence genes.
  • The findings revealed that a high percentage of the strains, especially E. faecalis and E. faecium, tested positive for multiple virulence genes, indicating their potential pathogenicity.

Persistent cellular stress induced perpetuation and uncontrolled amplification of inflammatory response results in a shift from tissue repair toward collateral damage, significant alterations of tissue functions, and derangements of homeostasis which in turn can lead to a large number of acute and chronic pathological conditions, such as chronic heart failure, atherosclerosis, myocardial infarction, neurodegenerative diseases, diabetes, rheumatoid arthritis, and cancer. Keeping the vital role of balanced inflammation in maintaining tissue integrity in mind, the way to combating inflammatory diseases may be through identification and characterization of mediators of inflammation that can be targeted without hampering normal body function. Pirin (PIR) is a non-heme iron containing protein having two different conformations depending on the oxidation state of the iron.

Salicylic acid (SA) serves as a pivotal plant hormone involved in regulating plant defense mechanisms against biotic stresses, but the extent of its biological significance in relation to peanut resistance is currently lacking. This study elucidated the involvement of salicylic acid (SA) in conferring broad-spectrum disease resistance in peanuts through the experimental approach of inoculating SA-treated leaves. In several other plants, the salicylate hydroxylase genes are the typical susceptible genes ( genes).

  • Early leaf spot disease, caused by the fungus Cercospora arachidicola, harms peanut crops, prompting the search for eco-friendly solutions like Bacillus bacteria instead of chemical fungicides.
  • The study identified Bacillus amyloliquefaciens TA-1 as a strong antagonist against the disease, achieving an impressive 95% biocontrol effect in greenhouse tests.
  • Whole-genome sequencing of TA-1 revealed it has a single circular chromosome with 4172 protein-coding genes and the potential to produce various antifungal metabolites.

  • Spinal anesthesia is safe for lumbar surgeries, even for patients with comorbidities like obesity, anxiety, and sleep apnea, challenging the notion that these factors increase complication risks.
  • A study analyzed 422 lumbar surgeries performed under spinal anesthesia, finding no significant differences in complications across various risk factor groups compared to a control group.
  • The findings suggest that spinal anesthesia can be a viable option for most patients with significant comorbidities, supporting its broader use in routine lumbar procedures.

Vitamin D-dependent Rickets Type II (VDDR-II) is a rare autosomal recessive disorder caused by a vitamin D receptor gene mutation, leading to end-organ resistance to 1,25-dihydroxyvitamin D 1,25(OH)2D. We aimed to investigate two cases of VDDR-II. Case 1 was of a 14-year old male, presenting with bone pains, bowing of legs, multiple bone deformities, and fractures since childhood.

Background: Spinal anesthesia is safe and effective in lumbar surgeries, with numerous advantages over general anesthesia (GA). Nevertheless, 1 major concern preventing the widespread adoption of this anesthetic modality in spine surgeries is the potential for intraprocedural anesthetic failure, resulting in the need to convert to GA intraoperatively.

A novel Bacillus amyloliquefaciens BAM strain, with novel fermentation nutrient mediums and compositions, could produce potent antifungal secondary metabolites, as the existing strains face resistance from fungus pathogens. In the current study, we introduced two novel nutrient mediums for the fermentation process, semolina and peanut root extract, as carbon and nitrogen sources in order to maximize the antifungal effects of B. amyloliquefaciens against Cercaspora arachidichola to control early leaf spot disease in peanuts.

Background: Pirin, a member of the cupin superfamily, is an iron-binding non-heme protein. It acts as a coregulator of several transcription factors, especially the members of NFκB transcription factor family. Based on the redox state of its iron cofactor, it can assume two different conformations and thereby act as a redox sensor inside the nucleus.

Objective: The extreme elderly population (≥80 years of age) is expected to triple globally by 2050 and surgeries in this age group are likely to increase. Spinal anesthesia has emerged as a safe and effective alternative to general anesthesia in lumbar surgery and may particularly benefit extreme elderly patients concerned with post-operative cognitive dysfunction, poor physiological reserves, and polypharmacy. However, literature supporting its use in this population is lacking and there are potential challenges such as degenerative anatomy and medical comorbidities.

Terpenoids from natural plant sources are valuable for their diverse biological activities that have important roles in the medical and agrochemical industries. In this study, we assessed the antioxidant, antifungal, and aphicidal activities of a mixture of spinasterol and 22,23-dihydrospinasterol from the leaves of Citrullus colocynthis. We used 1,1-diphenyl-2-picrylhydrazyl (DPPH) to assess antioxidant activity, and we measured antifungal activity using mycelium growth inhibition assays with three pathogenic fungi, Magnaporthe grisea, Rhizoctonia solani, and Phytophthora infestans.
