Secondary metabolites synthesized by endophytic fungi have garnered significant interest for their broad applications in treating various ailments. In this study involving 20 plant samples, 11 endophytic fungi were isolated and cultured, and Lasiodiplodia pseudotheobromae EF-9, derived from Hibiscus rosa-sinensis, demonstrated greater antibacterial efficacy than the other isolated endophytes. Phylogenetic analyses using 18S rRNA gene confirmed the EF-9 identity as L.

Article Synopsis
  • The study aimed to explore the agreement between intraocular pressure (IOP) measured with a scleral Schiotz tonometer and the more commonly used Goldmann applanation tonometer (GAT).
  • It involved 155 patients, measuring IOP through both methods, and analyzed factors like age and central corneal thickness to see their impact on IOP readings.
  • Results indicated that the scleral measurements aligned well with GAT values, suggesting that scleral tonometry could serve as a reliable alternative for measuring IOP in clinical settings.

Introduction The efficacy of wound-healing treatments can be significantly enhanced through innovative combination therapies. This research investigates the wound-healing properties of a combination therapy involving silver nanoparticles (AgNPs) synthesized using Delphinium denudatum (Dd), bovine tendon collagen (BTC), and the antibiotic doxycycline (DOX) in Wistar albino rats. Each component has known therapeutic benefits: AgNPs possess antimicrobial properties, BTC aids in tissue regeneration, and DOX is an effective antibiotic.

Bacterial species referred to as magnetotactic bacteria (MTB) biomineralize iron oxides and iron sulphides inside the cell. Bacteria can arrange themselves passively along geomagnetic field lines with the aid of these iron components known as magnetosomes. In this study, magnetosome nanoparticles, which were obtained from the taxonomically identified MTB isolate sp.

Context: It is well known that antibiotic resistance is a major health hazard. To eradicate antibiotic-resistant bacterial infections, it is essential to find a novel antibacterial agent. Hence, in this study, a quantitative structure-activity relationship (QSAR) model was developed using 43 DNA gyrase inhibitors, and 700 natural compounds were screened for their antibacterial properties.

Background: Two major avoidable reasons for adverse events in hospital are medication errors and intravenous therapy-induced infections or complications. Training for clinical staff and compliance to patient safety principles could address these.

Methods: Joint Commission International (JCI) consultants created a standardised, 6-month training programme for clinical staff in hospitals.

Hard ticks are mainly responsible for more "tick-borne" diseases in humans when compared to soft ticks. Tick infestation of ocular and periocular tissues is rare. We report the case of a 61-year-old male with left upper eyelid edema with erythema and live parasite on the lid margin.

Uveitis is a sight-threatening disease that causes inflammation in the uvea; difluprednate (DFB) is the first approved drug molecule for postoperative pain, inflammation, and endogenous uveitis. Complex ocular physiology and structure make it difficult to deliver drugs to the eye. Increased permeation and retention in the layer of the eye are required to improve the bioavailability of ocular drugs.

Psoriasis is an enduring, pruritic and papulosquamous skin ailment that poses a significant burden on public health. It is mainly characterized by hyperkeratosis, acanthosis, parakeratosis, scaly and erythematous plaques. Biomarkers like interleukin-17, interleukin-12 and -23 and tumor necrosis factor-α serve as key drivers of psoriatic pathogenesis.

Purpose: To compare the retinal sensitivities between the blue-on-yellow perimetry (BYP)/short-wavelength automated perimetry (SWAP) and green-on-yellow perimetry (GYP) among patients with and without nuclear sclerosis among glaucoma suspects.

Methods: After ophthalmic examination, patients were subjected to two perimetric tests: BYP and GYP. The visual field (VF) parameters were compared between the two perimeters (p < 0.

Background: Sexual dysfunction, a potential side effect of selective serotonin reuptake inhibitors (SSRIs), can lead to marital dissatisfaction in remitted depression patients, affecting their quality of life (QOL), and all of these are risk factors for treatment noncompliance. We aimed to estimate the proportion of female sexual dysfunction and its subtypes compared to the general population and correlate it with various factors, including marital satisfaction and QOL, in remitted depressive patients on SSRI treatment.

Methods: This analytical cross-sectional study assessed 116 women, comprising 58 patients aged 18- to 45 years with rsemitted depression on SSRI monotherapy for a minimum of six weeks and their age-matched comparative group.

Endophytic fungi were isolated from forty plant leaf samples from Gudiyam forest. The potent antibacterial strain Aspergillus niger E12 isolated from the plant Dodonaea viscosa showed maximal antibacterial activity against all the test organisms, viz., Staphylococcus aureus, Bacillus coagulans, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Magnetotactic bacteria (MTB) use iron from their habitat to create magnetosomes, a unique organelle required for magnetotaxis. Due to a lack of cost-effective assay methods for estimating iron in magnetosomes, research on MTB and iron-rich magnetosomes is limited. A systemized assay was established in this study to quantify iron in MTB using ferric citrate colorimetric estimation.

Aims: This study envisaged the isolation and characterization of magnetite nanoparticles (MNPs) from magnetotactic bacteria (MTB) and the evaluation of their antibacterial efficacy.

Methods And Results: MNPs were extracted from 20 motile but morphologically different MTB, and they were subjected to antibacterial activity assay. These MNPs were found to be highly effective against Vibrio cholerae.
