Additionally, we provide a perspective on examples of experimentally characterised RASopathy mutations that, alone or in combination with various stressors, may also trigger an age-dependent chronic senescence, possibly contributing to the age-dependent worsening of RASopathy pathophenotype and the reduction of lifespan.
Erythropoietin (EPO), the cytokine required for erythropoiesis, contributes to metabolic regulation of fat mass and glycemic control. EPO treatment in mice on high-fat diets (HFD) improved glucose tolerance and decreased body weight gain via reduced fat mass in males and ovariectomized females. BGJ398 purchase The decreased fat accumulation with EPO treatment during HFD in ovariectomized females was abrogated with estradiol supplementation, providing evidence for estrogen-related gender-specific EPO action in metabolic regulation. In this study, we examined the cross-talk between estrogen mediated through estrogen receptor α (ERα) and EPO for the regulation of glucose metabolism and fat mass accumulation.
Wild-type (WT) mice and mouse models with ERα knockout (ERα-/-) and targeted deletion of ERα in adipose tissue (ERα
) were used to examine EPO treatment during high-fat diet feeding and after diet-induced obesity.
ERα-/- mice on HFD exhibited increased fat mass and glucose intolerance. EPO treatment on HFD reduced fan fat mass regulation. Cross-talk between EPO and estrogen was implicated for metabolic homeostasis and regulation of body mass in female mice.
Edible mushrooms have a great nutritional value including high protein, essential amino acids, fiber, vitamins (B
, B
, B
, C, and D), minerals (calcium [Ca], potassium [K], magnesium [Mg], sodium [Na], phosphorus [P], copper [Cu], iron [Fe], manganese [Mn], and selenium [Se]), low fatty foods, and sodium. The objective of this systematic review was to determine the relationship between edible mushroom consumption and overall cardiovascular risk.
We systematically searched Ovid MEDLINE, Embase, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science from database inception from 1966 through August 2020 for observational studies that reported the association between edible mushroom consumption and cardiovascular risk. Two investigators independently reviewed data. Conflicts were resolved through consensus discussion.
Of 1479 studies, we identified 7 prospective studies. Edible mushroom consumption may have favorable effects on lipid profiles by changing some metabolic markers such as low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, total cholesterol, and triglycerides. Moreover, edible mushroom consumption is probably associated with reduced mean blood pressure. The beneficial overall cardiovascular risk, stroke risk, and coronary artery disease of edible mushroom consumption are not consistent.
Edible mushroom consumption has not been shown to conclusively affect cardiovascular risk factors to date. However, potential health benefits may exist, including a favorable alteration of lipid profiles and blood pressure reduction.

Vector competence of Cx. tritaeniorhynchus and Cx. quinquefasciatus was examined for DTMUV. Cx. tritaeniorhynchus mosquitoes were allowed to feed on four levels (102, 103, 104, and 105 TCID50/mL) of DTMUV, while Cx. quinquefasciatus were allowed to feed on two levels (104 and 105 TCID50/mL) of DTMUV. Infection rates in Cx. tritaeniorhynchus were 1.6, 10.2, 35.8, and 59.3% after feeding on 102, 103, 104, and 105 TCID50/mL of DTMUV, respectively, while dissemination and transmission were 20.3 and 16.9% after feeding on 105 TCID50/mL of DTMUV. Infection rates in Cx. quinquefasciatus were 2.5 and 2.3% after feeding on 104 and 105 TCID50/mL of DTMUV, respectively, with no virus dissemination and transmission found in all tested mosquitoes. Another study was conducted to examine the transovarial transmission of DTMUV in Cx. tritaeniorhynchus. Mosquitoes were allowed to feed on blood meal infected with 105 TCID50/mL of DTMUV. Each blood-fed mosquito was isolated and allowed to lay eggs. After oviparity, the mosquitoes were tested for DTMUV infection; 43 DTMUV infected and 37 non-infected female mosquitoes with eggs were included. A total of 182 F1 progeny from DTMUV infected mosquitoes and 145 F1 progeny from non-infected mosquitoes were tested for DTMUV but all were negative. Findings indicated the potential role of Cx. tritaeniorhynchus in the DTMUV transmission cycle in duck farms in Thailand. No transovarial transmission of DTMUV was found in Cx. tritaeniorhynchus.Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi and is endemic to many parts of the Asia-Pacific region. We investigated whether the genotype of O. tsutsugamushi or the DNA load would be a useful marker of disease severity in scrub typhus patients. We evaluated the clinical features, genotypes and bacterial DNA load in the blood of 118 patients, including 114 surviving and 4 non-surviving patients, admitted at Chosun University Hospital. Four patients infected with the Pajoo, Yonchon, Youngworl and Boryong genotypes died. In the 114 survivors, 100 Boryong and 2 Taguchi genotypes were identified. The genotypes involved showed significant differences between the surviving and non-surviving patients (p less then 0.001). The median number of O. tsutsugamushi DNA copies was 78 copies /μL (range 3,960) in surviving patients, whereas 83,800 copies/μL (range 244,600) in the non-surviving patients. We found that the genotype and DNA load in the patient's blood are useful markers of disease severity in scrub typhus.Ngari virus is a mosquito-borne virus belonging to the genus Orthobunyavirus (Peribunyaviridae family). This virus is pathogenic to humans and causes severe illness. Ngari virus is present in several African countries, including Madagascar. Here, we report the detection of Ngari virus in ixodid ticks collected from cows in Guinea. A tick survey was conducted in March-November of 2018 in six regions of Guinea. The sample comprised 710 pools, with a total of 2067 ticks belonging to five species collected from 197 cows. At the initial stage, we screened a subsample of tick pools of vector-borne viruses with a multiplex genus-specific primer panel. In the second stage of the study, we narrowed the search and screened all the samples by qPCR for the detection of Ngari virus. All positive samples were sequenced with primers flanking Ngari virus-specific fragments on the S and M segments. We found Ngari virus in 12 pools that were formed from engorged ticks collected from livestock in three villages of the Kindia and Kankan regions.
