A Case Report on Endometriosis-Associated Intestinal Tumour Following Hysterectomy: Diagnostic Challenges and Implications for Hormone Replacement Therapy (HRT) Guidelines.

Endometriosis is a complex condition that is often underdiagnosed, leaving rare but serious risks such as malignant transformation overlooked in many cases. Malignant transformation, especially in extra-gynaecological sites, poses significant diagnostic and therapeutic challenges. We present a case of an endometriosis-associated intestinal tumour diagnosed in a patient with exposure to oestrogen-only hormone replacement therapy (HRT) on a background of total abdominal hysterectomy and bilateral oophorectomy performed three decades before her presentation.

Bioprocessing of camptothecin from Alternaria brassicicola, an endophyte of Catharanthus roseus, with a strong antiproliferative activity and inhibition to Topoisomerases.

Suppression of fungal camptothecin (CPT) biosynthesis with the preservation and successive subculturing is the challenge that impedes fungi from the industrial application, so, screening for a novel fungal isolate with a conceivable stable producing potency of CPT was the main objective of this work. Catharanthus roseus with diverse contents of bioactive metabolites could have a plethora of novel endophytes with unique metabolic properties. Among the endophytes of C.

Camptothecin bioprocessing from Aspergillus terreus, an endophyte of Catharanthus roseus: antiproliferative activity, topoisomerase inhibition and cell cycle analysis.

Attenuation of camptothecin (CPT) productivity by fungi with preservation and subculturing is the challenge that halts fungi to be an industrial platform of CPT production. Thus, screening for novel endophytic fungal isolates with metabolic stability for CPT production was the objective. Catharanthus roseus is one of the medicinal plants with diverse bioactive metabolites that could have a plethora of novel endophytes with unique metabolites.

Using a stochastic continuous-time Markov chain model to examine alternative timing and duration of the COVID-19 lockdown in Kuwait: what can be done now?

Background: Kuwait had its first COVID-19 in late February, and until October 6, 2020 it recorded 108,268 cases and 632 deaths. Despite implementing one of the strictest control measures-including a three-week complete lockdown, there was no sign of a declining epidemic curve. The objective of the current analyses is to determine, hypothetically, the optimal timing and duration of a full lockdown in Kuwait that would result in controlling new infections and lead to a substantial reduction in case hospitalizations.
