Leptadenia reticulata (Retz.) Wight & Arn. (Apocynaceae), is a traditional medicinal plant species widely used to treat various ailments such as tuberculosis, hematopoiesis, emaciation, cough, dyspnea, fever, burning sensation, night blindness, cancer, and dysentery. In Ayurveda, it is known for its revitalizing, rejuvenating, and lactogenic properties. This plant is one of the major ingredients in many commercial herbal formulations, including Speman, Envirocare, Calshakti, Antisept, and Chyawanprash. The therapeutic potential of this herb is because of the presence of diverse bioactive compounds such as α-amyrin, β-amyrin, ferulic acid, luteolin, diosmetin, rutin, β-sitosterol, stigmasterol, hentricontanol, a triterpene alcohol simiarenol, apigenin, reticulin, deniculatin, and leptaculatin...

Pleural effusion is a common clinical manifestation with various causes. Current diagnostic and therapeutic methods have exhibited numerous limitations. By involving the analysis of dynamic changes in low molecular weight catabolites, metabolomics has been widely applied in various types of disease and have provided platforms to distinguish many novel biomarkers. However, to the best of our knowledge, there are few studies regarding the metabolic profiling for pleural effusion. In the current study, 58 pleural effusion samples were collected, among which 20 were malignant pleural effusions, 20 were tuberculous pleural effusions and 18 were transudative pleural effusions...

Lung cancer is the most common malignancy in humans. An increased population of CD4+Foxp3+ regulatory T cells (Tregs) in the tumor-associated microenvironment plays an important role in cancer immune evasion. The exact role and the involved mechanisms of concomitant H37Rv infection in non-small cell lung cancer (NSCLC) development are still not clear. Here, we showed that H37Rv infection promoted NSCLC cell growth with a higher percentage of Tregs found in draining lymph nodes. We also determined in vitro that H37Rv infection induced macrophage maturation and PD-L1 expression, which promoted Treg proportion, with enhanced proliferation suppression function...

Malignancy and tuberculosis are common causes of lymphocytic exudative pleural effusion. However, it is occasionally difficult to differentiate malignant pleural effusion from tuberculous pleural effusion. Vascular endothelial growth factor (VEGF) is a critical cytokine in the pathogenesis of malignant pleural effusion. Endocan is a dermatan sulfate proteoglycan that is secreted by endothelial cells. Importantly, endocan mediates the vascular growth-promoting action of VEGF. The aim of this study was to evaluate the diagnostic significance of VEGF and endocan in pleural effusion...

BACKGROUND Mucinous ovarian adenocarcinoma is one of the less common epithelial cancers of the ovaries, and typically does not occur in younger women. Nearly all mucinous ovarian adenocarcinomas present with early-stage disease without significant sequelae of cancer, such as clotting. Anchoring bias is a common problem in medicine that has been shown to significantly affect physician decision-making. CASE REPORT We present the case of a 24-year-old healthy female Chinese immigrant with no significant past medical history, who presented with a subacute history of nonproductive cough and shortness of breath with exertion...

Mycobacterium tuberculosis (M. tuberculosis) is one of the leading causes of morbidity and mortality. Currently, the emergence of drug resistance has an urgent need for new drugs. In previous study, we found that 1,2-di(quinazolin-4-yl)diselane (DQYD), a quinazoline derivative, has anticancer activities against many cancers. However, whether DQYD has the activity of antimycobacterium is still little known. Here our results show that DQYD has a similar value of the minimum inhibitory concentration with clinical drugs against mycobacteria and also has the ability of bacteriostatic activity with dose-dependent and time-dependent manner...

A small library of new 3-aryl-5-(alkyl-thio)-1H-1,2,4-triazoles was synthesized and screened for the anti-mycobacterial potency against M. tuberculosis H37 Ra strain and M. bovis BCG both in active and dormant stage. Among the synthesized library, 25 compounds exhibited promising anti-TB activity in the range of IC50 0.03-5.88 μg/mL for dormant stage and 20 compounds in the range of 0.03-6.96 μg/mL for active stage. Their lower toxicity (>100 μg/mL) and higher selectivity (SI = >10) against all cancer cell lines screened makes them interesting compounds with potential anti-mycobacterial effects...

Tobacco remains the key modifiable risk factor for the development of a number of diseases, including cardiovascular disease, cerebrovascular disease, lower respiratory infections, chronic obstructive pulmonary disease, tuberculosis and cancer. Among priority populations, smoking prevalence remains high, smokers tend to relapse more often and earlier and fewer are able to sustain quit attempts. This systematic review provides an update on the literature. Areas covered: Twenty-four randomized controlled trials published from 2010-2017, in English language, were identified after searching on Medline, Ovid, Embase and PsycINFO databases...

REVIEW
Lisa J Hill, Adrian C Williams
Meat and vitamin B3 - nicotinamide - intake was high during hunter-gatherer times. Intake then fell and variances increased during and after the Neolithic agricultural revolution. Health, height, and IQ deteriorated. Low dietary doses are buffered by 'welcoming' gut symbionts and tuberculosis that can supply nicotinamide, but this co-evolved homeostatic metagenomic strategy risks dysbioses and impaired resistance to pathogens. Vitamin B3 deficiency may now be common among the poor billions on a low-meat diet...

Antiretroviral therapy (ART) is recommended for all patients infected by HIV-1. The objective of ART is to achieve an undetectable plasma viral load (PVL). Initial ART should be based on a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors (tenofovir in either of its two formulations plus emtricitabine or abacavir plus lamivudine) and another drug from a different family. Four of the recommended regimens, all of which have an integrase inhibitor as the third drug (dolutegravir, elvitegravir boosted with cobicistat or raltegravir), are considered preferential, whereas a further 3 regimens (based on elvitegravir/cobicistat, rilpivirine, or darunavir boosted with cobicistat or ritonavir) are considered alternatives...

A 47-year-old man presented to the urology department with visible haematuria. He was found to have a high-grade non-muscle-invasive transitional cell carcinoma of the bladder and was subsequently treated with intravesical BCG instillations. On routine surveillance CT scan following treatment he was found to have multiple rounded areas of low density in the right kidney, suspicious for renal malignancy. He underwent renal biopsy which revealed necrotising granulomatous inflammation suggestive of mycobacterial infection...

Using a combination of mathematical modelling, statistical simulation and large-scale data analysis we study the properties of linear regulatory chains (LRCs) within gene regulatory networks (GRNs). Our modelling indicates that downstream genes embedded within LRCs are highly insulated from the variation in expression of upstream genes, and thus LRCs act as attenuators. This observation implies a progressively weaker functionality of LRCs as their length increases. When analyzing the preponderance of LRCs in the GRNs of Escherichia coli K12 and several other organisms, we find that very long LRCs are essentially absent...
