For multicellular organisms, much remains unknown about the dynamics of synonymous codon and amino acid use in highly expressed genes, including whether their use varies with expression in different tissue types and sexes. Moreover, specific codons and amino acids may have translational functions in highly transcribed genes, that largely depend on their relationships to tRNA gene copies in the genome. However, these relationships and putative functions are poorly understood, particularly in multicellular systems.

Here, we studied codon and amino acid use in highly expressed genes from reproductive and nervous system tissues (male and female gonad, somatic reproductive system, brain and ventral nerve cord, and male accessory glands) in the cricket Gryllus bimaculatus. We report an optimal codon, defined as the codon preferentially used in highly expressed genes, for each of the 18 amino acids with synonymous codons in this organism. The optimal codons were mostly shared among tissue types and both sexes. Hes, including optimal, wobble, and non-optimal codons, and their tRNA abundances, as well as amino acid use, have been influenced by adaptation for various functional roles in translation within this cricket. The effects of expression in different tissue types and the two sexes are discussed.
Collectively, the results suggest a model whereby codon use in highly expressed genes, including optimal, wobble, and non-optimal codons, and their tRNA abundances, as well as amino acid use, have been influenced by adaptation for various functional roles in translation within this cricket.

Intimate Partner Violence (IPV) is one of the most common forms of domestic violence, with profound implication for women's physical and psychological health. In this text we adopted the Empowerment Process Model (EPM) by Cattaneo and Goodman (Psychol Violence 5(1)84-94) to analyse interventions provided to victims of IPV by a Support Centre for Women (SCW) in Italy, and understand its contribution to women's empowerment.

We conducted semi-structured interviews with ten women who had been enrolled in a program for IPV survivors at a SCW in the past three years. The interviews focused on the programs' aims, actions undertaken to reach them, and the impact on the women's lives, and were analysed using an interpretative phenomenological approach.

Results showed that the interventions provided by the SWC were adapted according to women's needs. In the early phases, women's primary aim was ending violence, and the intervention by the SCW was deemed as helpful to the extent it provided psychological support, protection and safe housing. Women's aims subsequently moved to self-actualisation and economic and personal independence which required professional training, internships, and social support. Although satisfying the majority of the women's expectations, other important needs (e.g., economic support or legal services) were poorly addressed, and cooperation with other services (e.g., police or social services) was sometimes deemed as critical.

By evaluating a program offered by a SCW to IPV survivors through the lens of the EPM model, we found that women deemed the program as effective when both individual resources and empowerment processes were promoted. Strengths, limitations and implications are discussed.

Hypoxic stress plays a critical role in the persistence of Mycobacterium tuberculosis (Mtb) infection, but the mechanisms underlying this adaptive response remain ill defined.

In this study, using M. marinum as a surrogate, we analyzed hypoxic responses at the transcriptional level by Cappable-seq and regular RNA-seq analyses.

A total of 6808 transcriptional start sites (TSSs) were identified under normoxic and hypoxic conditions. Among these TSSs, 1112 were upregulated and 1265 were downregulated in response to hypoxic stress. Using SigE-recognized consensus sequence, we identified 59 SigE-dependent promoters and all were upregulated under hypoxic stress, suggesting an important role for SigE in this process. We also compared the performance of Cappable-seq and regular RNA-seq using the same RNA samples collected from normoxic and hypoxic conditions, and confirmed that Cappable-seq is a valuable approach for global transcriptional regulation analyses.

Our results provide insights and information for further characterization of responses to hypoxia in mycobacteria, and prove that Cappable-seq is a valuable approach for global transcriptional studies in mycobacteria.

Accurate diagnosis in patients with suspected coronavirus disease 2019 (COVID-19) is essential to guide treatment and limit spread of the virus. The combined nasal and throat swab is used widely, but its diagnostic performance is uncertain.

In a prospective, multi-centre, cohort study conducted in secondary and tertiary care hospitals in Scotland, we evaluated the combined nasal and throat swab with reverse transcriptase-polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in consecutive patients admitted to hospital with suspected COVID-19. Diagnostic performance of the index and serial tests was evaluated for a primary outcome of confirmed or probable COVID-19, and a secondary outcome of confirmed COVID-19 on serial testing. The diagnosis was adjudicated by a panel, who recorded clinical, laboratory and radiological features blinded to the test results.

We enrolled 1368 consecutive patients (median age 68 [interquartile range, IQR 53-80] years, 47% women)nasal and throat swab with RT-PCR for SARS-CoV-2 has excellent specificity, but limited diagnostic sensitivity for COVID-19. Diagnostic performance is significantly improved by repeated testing.
The primary aim was to observe the predictive value of P-wave ECG index and left atrial appendage volume (LLAV) for atrial fibrillation recurrence after first radiofrequency catheter ablation.

A total of 196 patients with paroxysmal atrial fibrillation were enrolled. The preoperative LLAV was measured by cardiac enhanced CT. The P-wave ECG index including minimum P-wave duration (P-min), maximum P-wave duration (P-max), mean P-wave duration (mPWD), P-wave dispersion (PWD), P-wave terminal force in lead V1 (PtfV1), PR interval prolongation, and interatrial block (IAB) were analyzed and recorded in 12-lead ECG of sinus rhythm.

According to the follow-up results, the patients were divided into two groups the non-recurrence group and the recurrence group. P-min, PWD, P-max, PtfV1 ≥ 0.04mV·s, PR interval prolongation, and the ratio of first and third-degree IAB in the recurrence group were higher than those in the non-recurrence group, with significant statistical differences (P < 0.05). Foxy-5 solubility dmso Kaplan-Meier curve analysis was performed on time to atrial fibrillation recurrence after catheter ablation when PtfV1 ≥ 0.04mvs by comparison between groups (Log Rank test 2 = 4.739, P < 0.001). Kaplan-Meier curve analysis showed that the survival rate without recurrence of atrial fibrillation after catheter ablation was lower when the LLAV exceeded 8.0mL (log-rank test P < 0.001).

PWD, P-max, PtfV1, PR interval prolongation, first and third-degree IAB, and LLAV can effectively predict atrial fibrillation recurrence after radiofrequency catheter ablation. The combination might be a valid and alternative independent predictor of recurrence.

Ectopic pancreas (EP) is defined as pancreatic tissue that lacks anatomical or vascular communication with the normal body of the pancreas. Despite improvements in diagnostic endoscopy and imaging studies, differentiating ectopic pancreatic tissue from gastric submucosal diseases remains a challenge.

Here, we present a case of a 44-year-old woman with severe epigastric pain. Initially, gastric lymphangioma was highly suspected due to a well-demarcated protruding mass with a large size that occurred in the submucosal layer of the gastric antrum and appeared as a cystic lesion. The final correct diagnosis of gastric EP was made during surgery.

Gastric EP with serous oligocystic adenoma appearing as a giant gastric cyst is extremely rare. The difficulty of making an accurate diagnosis and differential diagnosis is highlighted, which may provide additional clinical experience for the diagnosis of EP with serous oligocystic adenoma in the stomach.

DNA sequence composition affects meiotic recombination. However, the correlation between tandem repeat composition and meiotic recombination in common wheat (Triticum aestivum L.) is unclear.

Non-denaturing fluorescent in situ hybridization (ND-FISH) with oligonucleotide (oligo) probes derived from tandem repeats and single-copy FISH were used to investigate recombination in three kinds of the long arm of wheat 5A chromosome (5AL). 5AL
arm carries the tandem repeats pTa-535, Oligo-18, and pTa-275, 5AL
arm carries the tandem repeats pSc119.2, Oligo-18 and pTa-275, and 5AL
arm carries the tandem repeats pSc119.2. In the progeny of 5AL
 × 5AL
, double recombination occurred between pSc119.2 and pTa-535 clusters (119-535 interval), and between pTa-535 and Oligo-18/pTa-275 clusters (535-18 interval). The recombination rate in the 119-535 interval in the progeny of 5AL
 × 5AL
was higher than that in the progeny of 5AL
 × 5AL
. Recombination in the 119-535 interval produced 5AL
segments with pTa-5l to measure meiotic recombination and select parents for wheat breeding programs.
The elder population suffered from social, economic, and health (which includes physical) related problems. Thus, these problems are complex and interrelated, thereby requiring specific knowledge and expertise to meet them. However, there were limited researches previously done to explore nurse's knowledge towards geriatric care. Therefore, this study aimed to assess knowledge towards geriatric care and to examine its predictors in North east Ethiopia. The findings will be helpful to develop strategies that would promote nurses' knowledge, which in turn improves the quality of patient care and consequently, the health of older people.

A facility-based cross-sectional study was conducted from March 8 to 28, 2020, among 335 nurses. Simple random sampling technique was employed to select study participants. A structured self-administered questionnaire was used to collect data on knowledge of nurses towards older adult care. A multivariable logistic regression model was applied to identify significant predictors and P-value< 0.
