Trigonella foenum graecum is an Iranian medicinal plant used for the treatment of rheumatoid arthritis and inflammation. The present study was designed to investigate the beneficial outcome of the plant T. foenum graecum on adjuvant-induced arthritis in albino rats. Ethanol extract of T. foenum graecum was tested against Freund's complete adjuvant-induced arthritis in rats. In the present study, paw volume was measured on the 4th, 8th, 14th and 21st day. On day 22, animals were anaesthetized, and blood samples were collected for the estimation of haemoglobin, white blood cells (WBC), differential white blood cells, erythrocyte sedimentation rate (ESR), red blood cells (RBC), interleukins (IL-1α, IL-1β, IL-2, IL-6) and tumour necrosis factor-α (TNF-α). The animals were sacrificed, and the cartilage tissue was isolated for estimation of lipid peroxidation (LPO), superoxide dismutase (SOD) and glutathione (GSH). Administration with both doses of T. foenum graecum (200 and 400 mg/kg) significantly (P < 0.05) decreased the paw oedema and restored body weight. T. foenum graecum significantly (P < 0.05) reduced the differential WBC count, ESR and WBC (5.833 ± 0.703, 6.989 ± 58.5) content and also showed significant (P < 0.05) increase in RBC and Hb (4.783 ± 0.46, 15.46 ± 0.158) content. T. foenum graecum significantly (P < 0.05) decreased the IL-1α, IL-1β, IL-2, IL-6 and TNF-α levels. It also significantly decreased the levels of LPO and increased the SOD and GSH levels in cartilage tissue. In this study, T. foenum graecum 400-mg/kg dose showed more prominent results compared to the 200-mg/kg dose of T. foenum graecum. The results obtained in this study suggest that anti-inflammatory and antioxidant activities of T. foenum graecum may be the possible reason behind the observed anti-arthritic activity.

Nonsense mutations resulting in a premature stop codon in an open reading frame occur in critical tumor suppressor genes in a large number of the most common forms of cancers and are known to cause or contribute to the progression of disease. Low molecular weight compounds that induce readthrough of nonsense mutations offer a new means of treating patients with genetic disorders or cancers resulting from nonsense mutations. We have identified the nucleoside analog clitocine as a potent and efficacious suppressor of nonsense mutations. We determined that incorporation of clitocine into RNA during transcription is a prerequisite for its readthrough activity; the presence of clitocine in the third position of a premature stop codon directly induces readthrough. We demonstrate that clitocine can induce the production of p53 protein in cells harboring p53 nonsense-mutated alleles. In these cells, clitocine restored production of full-length and functional p53 as evidenced by induced transcriptional activation of downstream p53 target genes, progression of cells into apoptosis, and impeded growth of nonsense-containing human ovarian cancer tumors in xenograft tumor models. Thus, clitocine induces readthrough of nonsense mutations by a previously undescribed mechanism and represents a novel therapeutic modality to treat cancers and genetic diseases caused by nonsense mutations.

Nonsense mutations, resulting in a premature stop codon in the open reading frame of mRNAs are responsible for thousands of inherited diseases. Readthrough of premature stop codons by small molecule drugs has emerged as a promising therapeutic approach to treat disorders resulting from premature termination of translation. The aminoglycoside antibiotics are a class of molecule known to promote readthrough at premature termination codons. Gentamicin consists of a mixture of major and minor aminoglycoside components. Here, we investigated the readthrough activities of the individual components and show that each of the four major gentamicin complex components representing 92–99% of the complex each had similar potency and activity to that of the complex itself. In contrast, a minor component (gentamicin X2) was found to be the most potent and active readthrough component in the gentamicin complex. The known oto- and nephrotoxicity associated with aminoglycosides preclude long-term use as readthrough agents. Thus, we evaluated the components of the gentamicin complex as well as the so-called “designer” aminoglycoside, NB124, for in vitro and in vivo safety. In cells, we observed that gentamicin X2 had a safety/readthrough ratio (cytotoxicity/readthrough potency) superior to that of gentamicin, G418 or NB124. In rodents, we observed that gentamicin X2 showed a safety profile that was superior to G418 overall including reduced nephrotoxicity. These results support further investigation of gentamicin X2 as a therapeutic readthrough agent.

Background The ongoing COVID‐19 pandemic has greatly impacted the health services worldwide, challenging the way modern medicine has been practiced for decades. Aim The present study documents an institutional experience on its impact on cytology services. Materials & Methods The cytology samples received during lock down period in India (24 March to 17 May 2020) were analysis and compared to the samples received during the same time frame in year 2019. Results The data revealed an overall 92.6% reduction in cytology samples received. All sample types were reduced with a statically significant reduction in thyroid cytology samples (P‐value: .023). There was relative increase in breast and lymph node samples; however, this relative increase was not statistically significant. The malignancy rate also significantly increased by 34.1% accompanied by decrease in neoplastic category among the samples received during COVID‐19 lockdown period. Breast samples remain the most frequent sample type both in pre‐COVID‐19 and COVID‐19 periods. Majority of fine‐needle aspiration done in these cases, during the lockdown period, were either in cases for recurrence or primary diagnosis. Conclusion Prioritization of samples, proper precautions and triaging of patients before procedure helped in carrying out this procedure safely.

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of squamous cell carcinoma (SCC) of the oral cavity, larynx, oropharynx and hypopharynx was published in 2020. It was therefore decided by both the ESMO and the Korean Society of Medical Oncology (KSMO) to convene a special, virtual guidelines meeting in July 2021 to adapt the ESMO 2020 guidelines to consider the potential ethnic differences associated with the treatment of SCCs of the head and neck (SCCHN) in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with SCCHN (excluding nasopharyngeal carcinomas) representing the oncological societies of Korea (KSMO), China (CSCO), India (ISMPO), Japan (JSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence and was independent of the current treatment practices and drug access restrictions in the different Asian countries. The latter was discussed when appropriate. This manuscript provides a series of expert recommendations (Clinical Practice Guidelines) which can be used to provide guidance to health care providers and clinicians for the optimisation of the diagnosis, treatment and management of patients with SCC of the oral cavity, larynx, oropharynx and hypopharynx across Asia.
