Abstract:
Highlights: Rectal and vaginal swab specimens were collected from pregnant women and there was no significant difference in the proportion of group B Streptococcus isolation. Combined vaginal and rectal swab cultures provide a higher isolation of group B Streptococcus. Abstract : Group B Streptococcus is a Gram-positive bacterium found in women. It causes high-risk mortality in pregnant women, newborns, and the elderly. This study aimed to compare group B Streptococcus (GBS/Streptococcus agalactiae) proportions from different collection sites (vaginal and rectal swabs). This was an analytic ob

Abstract:
AbstractAs the pandemic situation continues, many people exercise at home. Mat Pilates is a popular workout and effective core strengthening. Although many researchers have conducted pose recognition studies for exercise posture correction, the study on Pilates exercise is only one case on static images. Therefore, for the purpose of exercise monitoring, we propose a real-time Pilates posture recognition system on a smartphone for exercise monitoring. We aimed to recognize 8 Pilates exercises—Bridge, Head roll-up, Hundred, Roll-up, Teaser, Plank, Thigh stretch, and Swan. First, the Blazepose model is used to extract body joint features. Then, we designed a deep neural network model that recognizes Pilates based on the extracted body features. It also measures the number of workouts, duration, and similarity to experts in video sequences. The precision, recall, and f1-score of the posture recognition model are 0.90, 0.87, and 0.88, respectively. The introduced application is expected to be used for exercise management at home.

Abstract:
Intestinal bacteria are among the most important natural bacteria present in animals especially sheep, forming part of the “microbiome”. This chapter aimed to assess the prevalence of antibiotic-resistant genes in Escherichia coli isolated from the intestines of imported sheep from the Western region of the Kingdom of Saudi Arabia (KSA). A total of 68 fecal (or rectal swab) samples were cultured to identify E. coli bacteria and their antibiotic susceptibility, and antibiotic resistance genes. High resistance was observed against ampicillin (88.5%), trimethoprim-sulfamethoxazole (80.8%), and cefuroxime (65.4%). Resistance to cefepime (61.5%) and levofloxacin (57.7%) was also significant. Molecular analysis of the antibiotic resistance genes in E. coli isolates revealed a high prevalence of sul2 (96.2%), followed by aadA1 (73.1%) and tet_A (65.4%). This study highlights the high prevalence of antibiotic-resistance genes in E. coli isolated from the intestines of sheep. The detection of multiple resistance genes, particularly those encoding sulfonamide and tetracycline resistance, suggests widespread antibiotic resistance. Additionally, the significant association between extended-spectrum beta-lactamase (ESBL) production and resistance to third- and fourth-generation cephalosporins underscores the need for stringent antibiotic stewardship in livestock management. There should be a strict monitoring of antibiotic use in animal farming and development of strategies to control the spread of resistant infections to ensure long-term food safety and human health. It is important to raise awareness and educating farmers, consumers, and health workers about the dangers of the overuse of antibiotics and the importance of maintaining food safety through good hygiene practices.

Abstract Recall from chapter 9, page 292, the remark: “I would also have wished to cover the black art of refereemanship, where even the minimal constraints imposed on scholars by the fact that their names will be publicly seen above their words are absent. Here truth counts for little and rhetoric holds sway.” This passage, which owed a great deal to Geoffrey K. Pullum, was, I will here argue, a bit prescient, supported by the subsequent appearance of the following successful anonymous referee subpassage, which was part of the most negative report (Overall Rating: Poor) received for my NSF Proposal SBR-9808169 (Diversity among English Objects). To facilitate its analysis and to justify my claim that this is junk refereeing, I have numbered the parts therein by associating a prefixed angle bracketed numeral with each or with major clauses within them: &amp;lt;1&amp;gt; In my opinion, the broader impact of this work will be negligible, &amp;lt;2&amp;gt; simply because the whole approach is founded upon assumptions that have not been current in the field for some time now. &amp;lt;3&amp;gt; The whole domain of the data presented here is now considered by 99% of researchers in the field &amp;lt;4&amp;gt; to involve complex relations between (at least) (i) phrase structure configurations (possibly of a quite ornate type), (ii) argument structure configurations and properties (highest/lowest argument, particular thematic relations), and (iii) more detailed semantic properties.

Abstract:
The Human, existed since millions of years and consequently, be inspired from the physiological phenomenon of the human body organs is something really interesting. This is the origin of the authors' new bio-inspired technique, called artificial haemostasis system (AHS), based on the haemostasis phenomenon that prevents and stops bleeding in case of external haemorrhage. Aiming at contributing to web searching they have applied their AHS to solve the problem of information retrieval following four steps: multilingual pre-processing (pre-haemostasis) to transform each text into a vector and ensure the service of multilingual search; The texts vectors pass through three filters: the primary information retrieval (primary haemostasis), the secondary information retrieval (secondary haemostasis) and the final information retrieval (fibrinolysis) using a selection step (plasminogen activation) to evaluate the relevance of each document to the query; the authors' experiments were performed on MEDLARS collection in order to show the benefit gained from using such approach compared to the classic one validated by a set of evaluation measures (recall, precision, FNR, FPR, f-measure, ROC, accuracy, Error, sensibility, and TCR); Finally, a result-mining step to see the results in graphical form with more realism, where the 3D cub method is largely preferred by the user than the cobweb method; The results of the system, are positive compared to the results provided by a conventional method and a set of bio-inspired techniques existed In literature (Simulating annealing (SA), Social worker bees (SWB), and Artificial social cockroaches (ASC)).
