Biotechnology offers a green alternative for the production of fuels and chemicals using microbes. Although traditional model hosts such as Escherichia coli and Saccharomyces cerevisiae have been widely studied and used, they may not be the best hosts for industrial application. In this review, we explore recent advances in the use of nonconventional hosts for the production of a variety of fuel, cosmetics, perfumes, food, and pharmaceuticals. Specifically, we highlight twenty-seven popular molecules with a special focus on recent progress and metabolic engineering strategies to enable improved production of fuels and chemicals. These examples demonstrate the promise of nonconventional host engineering. BACKGROUND A high sperm DNA fragmentation index (DFI) influences human reproduction and is observed in infertile men. However, the influence of DFI on unexplained recurrent spontaneous abortion (RSA) remains controversial. OBJECTIVE We explored the influence of DFI on unexplained recurrent spontaneous abortion. DATA SOURCES We conducted a meta-analysis of DFI (assessed by sperm chromatin structure assay(SCSA), terminal deoxynucleotidyl transferase-mediated deoxyuridine (TdT)triphosphate (dUTP) nick end labeling assay(TUNEL), sperm chromatin dispersion(SCD), single cell gel electrophoresis assay(COMET assay), and acridine orange test(AOT) with unexplained RSA from the Cochrane Library, EMBASE, Pubmed and Web of Science database. METHODS Records were screened for eligible studies and data were extracted to an online data extraction form. The main outcome was the sperm DFI. Summary measures were reported as the mean difference(MD) and Odds Ratio(OR) with 95 % confifidence interval (CI). RESULT We identified 27 articles including 3, 2, 9, 9, and 8 studies using AO, COMET, SCSA, SCD and TUNEL respectively; 7 articles used qualitative methods and 21 articles used in quantitative methods. The combined MD estimates of 7 SCSA studies (MD=5.4; 95 % CI 1.76-9.03; P less then 0.01), 9 SCD studies (MD=11.16; 95 % CI6.70-15.62; P less then 0.01), and 8 TUNEL studies (MD=12.12; 95 % CI 3.34-20.91; P less then 0.01) showed significant differences. Notably, qualitative studies showed consistent results with quantitative studies. CONCLUSION(S) These findings support an association between sperm DFI and recurrent pregnancy loss.

To celebrate the 25th anniversary of the cloning of the first mammalian p21-activated kinases (PAKs) (RAC/CDC42-activated kinases) by Ed Manser, the first international PAK symposium was held in NYC in October 2019. Among six distinct PAKs in mammals, PAK1 is the major 'pathogenic kinase', the abnormal activation of which is responsible for a wide variety of diseases and disorders including cancers, ageing processes and infectious and inflammatory diseases such as pandemic coronaviral infection. Recently, for a clinical application, a few potent (highly cell-permeable and water-soluble) PAK1 blockers have been developed from natural or synthetic PAK1 blockers (triptolide, vitamin D3 and ketorolac) via a series of 'chemical evolutions' that boost pharmacological activities &gt;500 times. Since 2005, H5Nx highly pathogenic avian influenza (HPAI) viruses of the Goose/Guangdong (Gs/GD) lineage have spread worldwide, affecting poultry and wild birds in Asia, Europe, Africa and North America. So far, the role of Western Asia and the Middle East in the diffusion dynamics of this virus has been poorly explored. In order to investigate the genetic diversity and the role of Iran in the transmission dynamics of the Gs/GD lineage, we sequenced the complete genome of twenty-eight H5Nx viruses which were circulating in the country between 2016 and 2018. We reported the first characterization of the HPAI H5N6 subtype of clade 2.3.4.4B in Iran and gave evidence of the high propensity of the Gs/GD H5 AIVs to reassort, describing six novel H5N8 genotypes of clade 2.3.4.4B, some of them likely generated in this area, and one H5N1 reassortant virus of clade 2.3.2.1c. Our spatial analyses demonstrated that the viruses resulted from different viral introductions from Asia and Europe and provided evidence of virus spread from Iran to the Middle East. Therefore, Iran may represent a hot-spot for virus introduction, dissemination and for the generation of new genetic variability. Increasing surveillance efforts in this high-risk area is of utmost importance for the early detection of novel emerging strains with zoonotic potential. The interaction between the activation of protein phosphatase, calcineurin (CaN), and the dephosphorylation and nuclear translocation of nuclear factor of activated T-cells (NFAT), a transcriptional factor in the immune system, has attracted interest as a key factor responsible for the cell death process. In this study, the effects of melatonin on the interaction between CaN and NFAT signaling during oxidative stress-induced cell death were investigated. Human neuroblastoma SH-SY5Y cells were treated with the non-radical reactive oxygen species hydrogen peroxide (H2O2). Cells were treated with 200 µM H2O2 for the indicated time. Some H2O2-treated cells were pretreated with melatonin for 1 hr. Control cells were treated with the same concentration of ethanol used to dilute melatonin. H2O2-induced cell death promoted increases in reactive oxygen species (ROS) production and the nuclear translocation of NFAT, which were related to increased levels the active, cleaved form of CaN (32.5 kDa). In addition, pretreatment of H2O2-treated cells with melatonin decreased cell death, ROS production, the levels of the active-cleaved form of CaN and the nuclear translocation of NFAT. Based on these findings, melatonin may exert its neuroprotective effects on oxidative damage-induced cell death by inhibiting CaN-activated the nuclear translocation of NFAT. V.Contrast-enhanced ultrasound with microbubbles has shown promise in detection of prostate cancer (PCa), but sensitivity and specificity remain challenging. Targeted nanoscale-contrast agents with improved capability to accumulate in tumors may result in prolonged signal enhancement and improved detection of PCa with ultrasound. Here we report nanobubbles (NB) that specifically targets prostate specific membrane antigen (PSMA) overexpressed in PCa. The PSMA-targeted-NB (PSMA-NB) were utilized to simultaneously image dual-flank PCa (PSMA-positive PC3pip and PSMA-negative PC3flu) to examine whether the biomarker can be successfully detected and imaged in a mouse model. Results demonstrate that active targeting rapidly and selectively enhances tumor accumulation and tumor retention. Importantly, these processes could be visualized and quantified, in real-time, with clinical ultrasound. Such demonstration of the immense yet underutilized potential of ultrasound in the molecular imaging area can open the door to future opportunities for improving sensitivity and specificity of cancer detection using parametric NB-enhanced ultrasound imaging. PURPOSE To modify and test the psychometric properties of the Chinese version of the Work Control Scale (C-WCS). METHODS The translated scale to administered to 840 nurses in Shanghai. Validity was assessed by content validity, construct validity including exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency and test-retest reliability were estimated by the Cronbach's α and the intraclass correlation coefficient (ICC). RESULT Psychometric analyses of the C-WCS indicate high reliability and good content and construct validity. CONCLUSIONS The C-WCS has good psychometric properties and can be used as a valid tool for measuring work control among nurses in China. The C-WCS will help further explore the correlations between perceived work control and organizational quality indicators such as nurses' satisfaction, job stress, wellbeing or intention to stay. It can also be used in nursing outcome studies of work control strategies. V.Females exhibit greater susceptibility to trauma- and stress-related disorders compared to males; therefore, it is imperative to study sex differences in the mode and magnitude of defensive responses in the face of threat. To test for sex differences in defensive behavior, we used a modified Pavlovian fear conditioning paradigm that elicits clear transitions between freezing and flight behaviors within individual subjects. Female mice subjected to this paradigm exhibited more freezing behavior compared to males, especially during the intertrial interval period. Female mice also exhibited more freezing in response to conditioned auditory stimuli in the last block of extinction training. Furthermore, there were sex differences in the expression of other adaptive behaviors during fear conditioning. Assaying rearing, grooming, and tail rattling behaviors during the conditioned flight paradigm yielded measurable differences across sessions and between males and females. Overall, these results provide insight into sex-dependent alterations in mouse behavior induced by fear conditioning. We attempted to establish a novel parameter of behaviour consistency to help determine the effect of age on physical activity. Using the speed of movement to quantify behaviour might not be sufficient to determine this effect. The slowing of motor activities that occurs with aging is related to the decline of the aging brain. Previous studies have found different running-related hippocampal theta rhythm responses in the aging and exercise model. Therefore, we hypothesized that a familiarity with the environment and physical strength affect behavioural consistency in rats during running exercises. For this study, we used a treadmill and 30-minute running test at constant speeds and compared changes in the triaxial accelerometer and hippocampal theta rhythm between adult and middle-aged rats. No significant differences in RR intervals, mean cross-correlations (MCCs), or the proportion of good correlation coefficient (PGCC) were observed between adult and middle-aged rats in awake states before running on the treadmill. The root mean square (RMS) of the triaxial acceleration vectors in middle-aged rats was higher than that in adult rats. In the treadmill running tests, the RMS observed in middle-aged rats was significantly lower than that observed in adult rats. MCC and PGCC, which indicate movement consistencies, were significantly higher in middle-aged rats than they were in adult rats during the entire running test. However, only the RMS of the adult rats showed a negative correlation with exercise duration. Both MCC and PGCC were positively correlated with exercise duration. By contrast, a similar phenomenon was not found in the changes or differences in hippocampal theta rhythms between these two groups. Therefore, we consider that the MCC and PGCC could distinguish age-related movement differences and indicate coordination/adaptation during exercise. Changes in physical activity and alterations in the hippocampal theta rhythm were not different between the groups. V.Is addiction a medical disorder, and if so, what kind of disorder is it? Addiction is considered a brain disease by NIDA, based on observed brain changes in addicts that are interpreted as brain damage. Critics argue that the brain changes result instead from normal neuroplasticity and learning in response to the intense rewards provided by addictive substances, thus addiction is not a disorder but rather a series of normal-range if problematic choices. Relying on the harmful dysfunction analysis of medical disorder to determine disorder versus nondisorder, I argue that even if one accepts the critics' reinterpretation of NIDA's brain evidence and rejects the brain disease account, the critics' conclusion that addiction is not a medical disorder but is rather a matter of problematic nondisordered choice does not follow. This is because there is a further possible account of addiction, the evolutionary "hijack" view, that holds that addiction is due to the availability of substances and stimuli that were unavailable during human species evolution and that "hijack" certain brain areas concerned with human motivation, creating biologically undesigned peremptory desires.
