The emergence and spread of multidrug-resistant bacteria is a major public health concern. This study sought to investigate the phenotypic and genotypic characteristics of clinical isolates of ESBL-producing Klebsiella pneumoniae, at University Hospital of Tizi-Ouzou. Antibiotic susceptibility testing of the strains was carried out by the disc diffusion method, the ESBL production was screening by the Double Disc Synergy Test and confirmed by the Phenotypic Confirmatory Disc Diffusion Test. Genomic DNA was extracted using the Qiagen DNeasy Blood & Tissue Kit mini kit (Qiagen) according to the manufacturer's instructions.PCR targeting the genes blaCTX-M, blaTEM, blaSHV, blaVEB, blaGES, blaPER, blaBEL, blaVIM, blaIMP, blaKPC, blaNDM and blaOXA48 was performed. A CTX-M PCR-based grouping method was carried out using primers specific to the groups 1, 2 and 9. Conjugative transfer of plasmids was carried out using sodium azide-resistant recipient strain Escherichia coli K12. The phylogenetic relationship was determined by ERIC-PCR. All strains of K. pneumoniae tested shared ESBL producer's genes belonging to the CTX-M group 1. These strains showed a high level of resistance to íŸ-lactams, aminoglycosides, fluoroquinolones and trimethoprim/ sulfamethoxazole. Resistance to fosfomycin was also detected in one strain of K. pneumoniae. Only one carbapenem-resistant strain was isolated. Phylogenetic analysis showed 49 different genetic profiles of K. pneumoniae strains, showing the absence of clonality. This study revealed a high prevalence of ESBL belonging to the CTX-M group 1 in K. pneumoniae tested. The emergence of resistance to carbapenem and fosfomycin, could seriously limits the therapeutic choices options.

Abstract
Venckunas, T, Bruzas, V, Stasiulis, A, Snieckus, A, Mockus, P, and Kamandulis, S. Cardiorespiratory responses to specific and non-specific exercise in high-profile amateur boxers. J Strength Cond Res 36(3): 717–722, 2022—Our aim was to compare cardiorespiratory responses in 3 types of all-out exercises (upper body, lower body, and punching) in well-trained boxers and peak heart rate (HR) in these tests with HR response to competitive Olympic boxing. On 4 separate occasions, 11 male amateur boxers performed: (a) progressive treadmill running to exhaustion; (b) progressive arm cranking to failure; (c) progressive bag punching to maximal exertion; and (d) competitive boxing fight (3 × 3 minutes format). Expired gas and HR were measured in all tasks except in the full-contact competitive fight where only HR was recorded. Peak oxygen uptake (55.3 ± 5.9 ml·kg−1·min−1) was highest during treadmill running. Peak respiratory exchange ratio was highest during bag punching (1.26 ± 0.09), but did not differ between arm cranking and running. Peak HR of the boxing fight (197.7 ± 5.9 b·min–1) did not differ from that of running (196.5 ± 8.7 b·min–1), but was smaller in arm cranking (179.8 ± 9.2) and bag punching (184.1 ± 12.2 b·min–1). The correlation coefficients between peak HR achieved during competitive fighting and that achieved during running, arm cranking and bag punching were 0.720 (p = 0.013), 0.597 (p = 0.052), and 0.702 (p = 0.035), respectively. In conclusion, in high-profile amateur boxers, running evoked a higher cardiorespiratory activation than arm cranking or bag punching, whereas punching elicited the highest input of anaerobic glycolysis. Peak HR of competitive fighting was the same as during running and much higher than during arm cranking or bag punching.

AbstractSleep spindles are distinctive transient patterns of brain activity that typically occur during non-rapid eye movement (NREM) sleep in humans and other mammals. Thought to be important for the consolidation of learning, they may also be useful for indicating the progression of aging and neurodegenerative diseases. The aim of this study was to characterize sleep spindles in sheep (Ovis aries). We recorded electroencephalographs wirelessly from six sheep over a continuous period containing 2 nights and a day. We detected and characterized spindles using an automated algorithm. We found that sheep sleep spindles fell within the classical range seen in humans (10–16 Hz), but we did not see a further separation into fast and slow bands. Spindles were detected predominantly during NREM sleep. Spindle characteristics (frequency, duration, density, topography) varied between individuals, but were similar within individuals between nights. Spindles that occurred during NREM sleep in daytime were indistinguishable from those found during NREM sleep at night. Surprisingly, we also detected numerous spindle-like events during unequivocal periods of wake during the day. These events were mainly local (detected at single sites), and their characteristics differed from spindles detected during sleep. These “wake spindles” are likely to be events that are commonly categorized as “spontaneous alpha activity” during wake. We speculate that wake and sleep spindles are generated via different mechanisms, and that wake spindles play a role in cognitive processes that occur during the daytime.

Abstract
Live traps usually can only trap rats in the first day of trapping because the bait become not luring anymore after the first day of trapping. The purpose of this study was to determine the differences in lured rats number between uncombined bait trapping and combined bait trapping.
This is a quasi-experimental study with a post-test only non-equivalent control group design. Each house has 5 traps setup with 6 replications. One trap was set with combined bait types (rice, anchovy, tofu and roasted coconut) and four other traps set with separated uncombined bait types; (1) rice, (2) anchovy, (3) tofu, (4) roasted coconut. The instruments used were house screening sheets, traps and observation sheets. The data obtained were tested with the Mann-Whitney test.
The results showed that there were not significant differences in trapped rats number between combined bait and uncombined rice bait (p=0.748), between combined bait and uncombined anchovy bait (p=0.355), between combined bait and uncombined tofu bait (p=1.000), and also between combined bait and uncombined roasted coconut bait (p=0.734). Uncombined anchovies bait trapped rats most. Combined bait and uncombined anchovy bait were most consistent in trapping rats.

This study aimed to investigate the correlation between social anxiety and self-esteem among the special need university students from Peshawar city, Khyber Pakhtunkhwa, Pakistan. The sample size was comprised of 100 disable university students aged 18-30 years, out of which 50 were male and 50 were female. A correlational study was designed. The social anxiety levels of the recruited subjects were determined through Liebowitz Social Anxiety Scale. The level of self-esteem was determined through the standard self-report mechanism by applying the Rosenberg Self-esteem Scale. The data collected were tabulated, analyzed and interpreted through SPSS software, Version 23, for windows, by using means, percentages, Pearson’s product-moment correlation coefficient (r) and Independent sample t-test. On average, the students with high social anxiety and low levels of self-esteem were found (r = -620), social anxiety of female students was high (M=78.14, SD=14.67) as compared to male students (M=59.34, SD=14.41). However, the self-esteem of female students (M=16.08, SD=1.77) was the same as compared with male students (M=16.38, SD= 1.86). There was a significant negative relationship found between social anxiety and self-esteem. The social anxiety of female disable university students was high, however, the male and female disable university students have the same self-esteem. Further studies are recommended on a large scale to explore certain other issues that are related to the given variables.
