Acupuncture is used in the treatment of a variety of inflammatory conditions and diseases. However, the mechanisms of its anti-inflammatory action are complex and have not been systematically investigated. Macrophages are key components of the innate immune system, thus, balancing the M1/M2 macrophage ratio and modulating cytokine levels in the inflammatory environment may be desirable therapeutic goals. Evidence has shown that acupuncture has anti-inflammatory actions that affect multiple body systems, including the immune, locomotory, endocrine, nervous, digestive, and respiratory systems, by downregulating pro-inflammatory M1 and upregulating anti-inflammatory M2 macrophages, as well as by modulating associated cytokine secretion. Macrophage polarization is controlled by the interlocking pathways of extrinsic factors, the local tissue microenvironment, and the neural-endocrine-immune systems. It has been suggested that polarization of T lymphocytes and cytokine secretions resulting in modulation of the autonomic nervous system and the hypothalamic-pituitary-adrenal axis, may be upstream mechanisms of acupuncture-induced macrophage polarization. We further propose that macrophage polarization could be the principal pathway involved in acupuncture immune regulation and provide the scientific basis for the clinical application of acupuncture in inflammatory conditions.

The probability of not breastfeeding within the first hour after delivery (timely initiation of breastfeeding) is particularly pronounced in sub-Saharan Africa. In this study, we examined the maternal and child factors associated with timely initiation of breastfeeding in sub-Saharan Africa.

We pooled data from 29 sub-Saharan African countries' Demographic and Health Surveys conducted from 2010 to 2018.A total of 60,038 childbearing women were included. Frequencies, percentages, and binary logistic regression analyses were carried out.Binary logistic regression was used to examine the maternal and child factors associated with timely initiation of breastfeeding and the results were presented as adjusted odds ratios (aOR) at 95% confidence interval (CI). RESULTS We found a prevalence of 55.81% of timely initiation of breastfeedingin the sub-region. ALK inhibitor The country with the highest prevalence of timely initiation of breastfeeding was Burundi (86.19%), whereas Guinea had the lowest prevalence (15.17%). The likel particularly among Cental African countries where timely initiation of breastfeeding remains a challenge. Sufficient supportive care, especially for mothers with multiple birthsand those who undergo caesarean section, is needed to resolve timely initiation of breastfeeding inequalities.

The findings call for the need for a behavioural change communication programmes, targeted at timely initiation of breastfeeding, to reverse and close the timely initiation of breastfeeding gaps stratified by the maternal and child factors. Prioritising policies to enhance timely initiation of breastfeeding is needed, particularly among Cental African countries where timely initiation of breastfeeding remains a challenge. Sufficient supportive care, especially for mothers with multiple births and those who undergo caesarean section, is needed to resolve timely initiation of breastfeeding inequalities.

Preclinical studies demonstrated that glucagon-like peptide 1 (GLP-1) is locally synthesized in taste bud cells and that GLP-1 receptor exists on the gustatory nerves in close proximity to GLP-1-containing taste bud cells. This local paracrine GLP-1 signalling seems to be specifically involved in the perception of sweets. However, the role of GLP-1 in taste perception remains largely unaddressed in clinical studies. Whether any weight-reducing effects of GLP-1 receptor agonists are mediated through the modulation of taste perception is currently unknown.

This is an investigator-initiated, randomized single-blind, placebo-controlled clinical trial. We will enrol 30 women with obesity and polycystic ovary syndrome (PCOS). Participants will be randomized in a 11 ratio to either semaglutide 1.0 mg or placebo for 16 weeks. The primary endpoints are alteration of transcriptomic profile of tongue tissue as changes in expression level from baseline to follow-up after 16 weeks of treatment, measured by RNA sequencing, and change in taste sensitivity as detected by chemical gustometry. Secondary endpoints include change in neural response to visual food cues and to sweet-tasting substances as assessed by functional MRI, change in body weight, change in fat mass and change in eating behaviour and food intake.

This is the first study to investigate the role of semaglutide on taste perception, along with a neural response to visual food cues in reward processing regions. The study may identify the tongue and the taste perception as a novel target for GLP-1 receptor agonists.

The study has been approved by the Slovene National Medical Ethics Committee and will be conducted in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. Results will be submitted for publication in an international peer-reviewed scientific journal.

CMTM7 is a tumor suppressor that positively regulates EGFR degradation by promoting Rab5 activation, and plays a vital role in tumor progression. Rab5 forms complexes with Beclin1 and VPS34, and acts in the early stage of autophagy. However, the affects of CMTM7 on autophagy and its mechanism are still unclear.

The effect of CMTM7 on autophagy induction was confirmed by western blotting, confocal microscopy and transmission electron microscopy. Co-immunoprecipitation was used to analyse the interaction of CMTM7 with autophagy initiation complex and Rab5. The xenograft model in nude mice was used to elucidate the function of CMTM7 in tumorigenicity and autophagy in vivo.

In this study, we first demonstrated that CMTM7 facilitated the initiation of autophagosome formation, which consequently promoted the subsequent multistage process of autophagic flux, i.e. from autophagosome assembly till autolysosome formation and degradation. Confocal and co-immunoprecipitation showed that CMTM7 interacted with Rab5, VPS34, Beclin1, and ATG14L, but not with ULK1, UVRAG and LC3B.
