Five different peptide amphiphiles with a general chemical formula [HN-(CH)CONH-Phe-CONHC (n = 1-5, C = dodecylamine)] have been synthesized, characterized, and examined for self-assembly and hydrogelation. All of these molecules [P1 (n = 1), P2 (n = 2), P3 (n = 3), P4 (n = 4), P5 (n = 5)] form thermoresponsive hydrogels in water (pH 6.

Topical azole antifungals are commonly used in their treatment but literature suggests that most require twice-daily application and provide lower cure rates than the allylamine antifungal terbinafine. We conducted a head-to-head comparison of the effectiveness of the once-daily topical azole, sertaconazole, with terbinafine in these infections.

She also presented with swelling of the lips and redness of both eyes along with nausea, anorexia, slight headache, and fever, which appeared immediately after the initiation of a new regime of antiretroviral treatment with tenofovir (300 mg once daily), lamivudine (300 mg once daily), and efavirenz (600 mg once daily). Presumptive diagnosis of efavirenz-induced Stevens-Johnson syndrome was made after excluding other causes.

All hematological and biochemical profiles were found to be normal. On discontinuation of risperidone, the condition remained unresolved even after 2 weeks, and the edema progressed reaching her calves.

Drug-induced bullous pemphigoid eruptions are rare but have been reported earlier with the use of frusemide, psoralens, ibuprofen, galantamine hydrobromide, ACE inhibitors like captopril, spironolactone, penicillin, ampicillin, levofloxacin, penicillamine. We hereby report a case of metronidazole induced bullous pemphigoid (BP) in a 52-year-old male patient suffering from liver abscess following 4 days of drug administration.

The purpose of this study was to identify C-deletion mutation in exon 4 codon 63 of p53 gene in the saliva of OSCC patients by polymerase chain reaction (PCR).
Materials And Methods: Saliva samples of 20 newly histopathologically diagnosed OSCC patients and 5 healthy volunteers were subjected to isolation of the total genomic DNA and PCR amplification for C-deletion on exon 4 of p53 gene.
Hoppea fastigiata, an annual medicinal herb belonging to the Gentianaceae, is mostly found in South Asian countries, and is used by local tribes for various brain-related ailments. The genus possesses a unique class of compounds, xanthones, which are known for their potential against Alzheimer's and Parkinson's diseases. Limited availability and the potential pharmacological significance of the plants has led to the establishment of in vitro cultures of H.

Materials And Methods: A total of 200 clinicians from core clinical disciplines was approached in six teaching hospitals of Kolkata through purposive sampling. A structured, validated questionnaire adopted from published studies and modified to suit the responding population was completed by consenting respondents through face-to-face interaction with a single interviewer.
Unlike carbamazepine, newer anti epileptic drug like oxcarbazepine, reports fewer side effects. In this report we describe a case of oxcarbazepine induced maculopapular rash probably happened because of a drug interaction with isoniazid, and a brief review of the existing literature is presented herewith. A 40-year-old male patient received oxcarbazepine 300mg twice daily along with other anti-tubercular drugs including isoniazid (300mg) once daily since two days.

Each time, he experienced fixed drug eruptions that increased in number and severity on subsequent occasions. Suspecting association between the drug and the rashes, the patient each time discontinued the treatment prematurely, and preferred to switch to a similar formulation next time, but with different molecules of fluoroquinolone (ciprofloxacin or ofloxacin) and nitroimidazole (tinidazole or ornidazole).

A careful literature search revealed that only a few reports of diclofenac induced and one case of serratiopeptidase associated case report of SJS or TEN have been published till date. However, to our knowledge, no case report of diclofenac-serratiopeptidase combination induced SJS have been published till date.

The main objective of the present study was to partially characterise this antifungal compound by UV-visible, IR, (1)H NMR, (13)C NMR and GC/MS analyses and also to assess its potentiality against a number of food spoilage, plant-pathogenic and human-pathogenic fungal species.
Results: The strain produced a broad-spectrum antifungal compound(s) that was induced by certain constituent factors of MRS and malt extract media.
A potentially novel antimicrobial compound producing Pediococcus acidilactici LAB 5 was isolated from vacuum-packed fermented meat product. This compound was found active against some species of Enterococcus, Leuconostoc, Staphylococcus and Listeria, many of which are associated with food spoilage and food related health hazards. The strain was found to be a paired cocci which can utilize a broad range of carbohydrates and produce acid identical to the P.
