Antimicrobial resistance (AMR) and persistence are associated with an elevated risk of treatment failure and relapsing infections. They are thus important drivers of increased morbidity and mortality rates resulting in growing healthcare costs. Antibiotic resistance is readily identifiable with standard microbiological assays, and the threat imposed by antibiotic resistance has been well recognized. Measures aiming to reduce resistance development and spreading of resistant bacteria are being enforced. However, the phenomenon of bacteria surviving antibiotic exposure despite being fully susceptible, so-called antibiotic persistence, is still largely underestimated. In contrast to antibiotic resistance, antibiotic persistence is difficult to measure and therefore often missed, potentially leading to treatment failures. In this review, we focus on bacterial mechanisms allowing evasion of antibiotic killing and discuss their implications on human health. We describe the relationship between antibiotic persistence and bacterial heterogeneity and discuss recent studies that link bacterial persistence and tolerance with the evolution of antibiotic resistance. Finally, we review persister detection methods, novel strategies aiming at eradicating bacterial persisters and the latest advances in the development of new antibiotics.The octahedral structure of 2D molybdenum disulfide (1T-MoS2 ) has attracted attention as a high-efficiency and low-cost electrocatalyst for hydrogen production. However, the large-scale synthesis of 1T-MoS2 films has not been realized because of higher formation energy compared to that of the trigonal prismatic phase (2H)-MoS2 . Ravoxertinib In this study, a uniform wafer-scale synthesis of the metastable 1T-MoS2 film is performed by sulfidation of the Mo metal layer using a plasma-enhanced chemical vapor deposition (PE-CVD) system. Thus, plasma-containing highly reactive ions and radicals of the sulfurization precursor enable the synthesis of 1T-MoS2 at 150 °C. Electrochemical analysis of 1T-MoS2 shows enhanced catalytic activity for the hydrogen evolution reaction (HER) compared to that of previously reported MoS2 electrocatalysts 1T-MoS2 does not transform into stable 2H-MoS2 even after 1000 cycles of HER. The proposed low-temperature synthesis approach may offer a promising solution for the facile production of various metastable-phase 2D materials.

Late-onset hypogonadism in men is related to the development of diabetes. The association of gonadal hormones, sex hormone binding globulin with diabetes has been studied in various studies. However, there is no cohort study on the relationship between gonadal hormone, sex hormone binding globulin and diabetes in Chinese. We aimed to provide an insight into the possible association in middle-aged and elderly Chinese males.

We included a population sample of 673 subjects aged 40years or older. Total testosterone (TT), sex hormone binding globulin (SHBG), follicle-stimulating hormone (FSH) and luteinising hormone (LH) were detected. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated to estimate insulin sensitivity. Diabetes was diagnosed according to the 2010 American Diabetes Association criteria.

With an average follow-up time of 3.2±0.5years, 9.8% of participants had developed diabetes. The prevalence of diabetes was decreased according to increasing SHBG quartiles (Q113.1%, Q2 12.0%, Q3 11.2%, Q4 3.0%, P for trend<.0001) and TT (Q116.0%, Q2 7.9%, Q3 9.0%, Q4 6.4%, P for trend<.0001). The ORs of diabetes for increasing SHBG quartiles were 4.52 (95% CI 1.40-14.57), 4.32 (95% CI 1.33-14.06), 3.89 (95% CI 1.21-12.50) and 1.00 (reference) respectively. But the odds of prevalent diabetes were not increased in different quartiles of TT, FSH and LH. In subgroup analyses, the relationship between SHBG and risk of incident diabetes was significantly increased in the population aged over 60, without insulin resistance and with eGFR<90mL/min per 1.73m

.

Compared with gonadal hormones, a lower level of SHBG is independently associated with the risk of diabetes in middle-aged and elderly Chinese males.

Here, a procedure was developed that could fabricate a single phase of α-Cu2 Se1-x Tex (x=0.02 and 0.04) by room-temperature aqueous synthesis using NaBH4 as reducing agent followed by cold pressing and sintering at 650 °C for 6 h in a flowing gas mixture of 20 % H2 and 80 % N2 . The energy-efficient synthesis carried out at room temperature abides by the 6th principle for green chemistry with less energy consumption. The reaction mechanism was studied, and evidence was provided of α-Cu2 Se being formed via the reaction between elemental Cu and Se atoms at room temperature. The resulting materials were characterized by powder X-ray diffraction, field-emission scanning electron microscopy, thermoelectric transport measurements, and Hall measurements. Cu1.96 Se0.96 Te0.04 had the highest power factor of 11 μW cm-1 K-2 at 818 K, and Cu2 Se0.96 Te0.04 had the maximum zT≥1.4 at T≥920 K among this series of materials.

This trial evaluated the addition of cetuximab to a modified FOLFOXIRI (mFOLFOXIRI 5-fluorouracil/folinic acid, oxaliplatin, irinotecan) as conversion therapy in a two-group, nonrandomized, multicenter, phase II trial in patients with initially technically unresectable colorectal liver-limited metastases (CLM) and BRAF/RAS wild-type.

Patients were enrolled to receive cetuximab (500 mg/m

) plus mFOLFOXIRI (oxaliplatin 85 mg/m

, irinotecan 165 mg/m

, folinic acid 400 mg/m

, 5-fluorouracil 2,800 mg/m

46-hour infusion, every 2 weeks) (the cetuximab group) or the same regimen of mFOLFOXIRI alone (the control group), in a 21 ratio allocation. The primary endpoint was the rate of no evidence of disease (NED) achieved. Secondary endpoints included resection rate, objective response rate (ORR), survival, and safety.

Between February 2014 and July 2019, 117 patients were registered for screening at six centers in China, and 101 of these were enrolled (67 cetuximab group, 34 control group). The rate of NED achieved was 70.
