Genome-wide analysis and characterization of HSP gene families (HSP20, HSP40, HSP60, HSP70, HSP90) in the yellow fever mosquito (Aedes aegypti) (Diptera: Culicidae).

The heat shock protein (HSP) gene families, present across prokaryotes to eukaryotes, play vital roles in growth, development, and heat resistance processes. While HSP proteins have been identified and characterized in various species, this study achieved the first genome-wide identification and characterization of HSP proteins in the Aedes aegypti genome. This study identified and assessed 80 potential HSP genes in Ae. aegypti. The phylogenetic relationships of HSP genes were investigated in Ae. aegypti, Anopheles stephensi, and Drosophila melanogaster. Additionally, the structural features, chromosomal locations, protein characteristics, 3D structure, protein-protein interactions, and microsatellites associated with HSP proteins were examined in Ae. aegypti. The phylogenetic analysis of HSP gene families revealed distinct intra-group relationships for each HSP group. Each family exhibited relatively conserved genetic structures and motif components. In the expression analysis of growth and development, high expression was observed in certain HSP20 and HSP70 genes, while others exhibited low expression. Notably, sex-dependent expression differences were observed, particularly in HSP20 genes. These findings, the relationships, evolution, and modification of HSP gene families are illuminated by these comprehensive findings, and a better understanding of the mechanisms underlying growth, development, and heat resistance in vector organisms is facilitated.

Validity and reliability of "My Jump app" to assess vertical jump performance: a meta-analytic review.

This systematic review and meta-analysis aims to investigate the validity and reliability of the My Jump smartphone application in measuring vertical jump height, specifically using flight-time-based measures. To identify potential studies for inclusion, a comprehensive search strategy was employed in PubMed, Web of Science, Scopus, and EBSCO host databases. Validity was assessed in two ways: (1) mean and standard deviations of My Jump measurements were compared to criterion methods to assess the agreement of raw scores; (2) correlation coefficients evaluated the within-group consistency of rankings between My Jump and criterion methods. Reliability was assessed using intraclass correlation coefficients (ICC). Heterogeneity was evaluated via Cochrane's Q statistic, its p-value, I2 value, and tau2 value. Publication bias was explored through funnel plot symmetry and confirmed with extended Egger's test. Following the search, 21 studies met the inclusion criteria. Results showed no significant difference in raw scores between My Jump and criterion methods, indicating high agreement. High correlation was also found for within-group rankings, suggesting consistency. The My Jump application demonstrated nearly perfect reliability scores. The My Jump application appears to be a valid and reliable tool for sports scientists and strength and conditioning practitioners, offering a cost-effective and accessible means for accurately assessing vertical jump performance in various settings. However, it should be noted that these results are specific to flight-time-based measures, and further research is needed to validate these findings against gold-standard take-off velocity methods.

The role of makorin ring finger protein-3, kisspeptin, and neurokinin B in the physiology of minipuberty.

BACKGROUND: There is no data regarding the interrelationships of circulating Makorin Ring Finger Protein-3 (MKRN3), Kisspeptin (KISS1), and Neurokinin B (NKB) concentrations during minipuberty in humans. OBJECTIVE: To determine temporal changes in circulating concentrations of MKRN3, KISS1, NKB, and gonadotropins and investigate interrelationships between them in healthy full-term (FT) and preterm (PT) infants during minipuberty period. METHODS: A prospective study of 6-month follow-up performed. Eighty-seven healthy newborns, 48 FT (19 boys/29 girls), and 39 PT (21 boys/18 girls) (gestational age 31-37 weeks), were included. Blood samples were taken at 7 days (D7), 2 months (M2), and 6 months (M6) of age. Serum MKRN3, KISS1, NKB, LH, FSH, total testosterone (TT), and estradiol (E2) concentrations were measured. RESULTS: Seventy infants completed the study. MKRN3, KISS1, and NKB concentrations were similar in FT girls and boys. PT boys and girls also had similar concentrations of MKRN3, KISS1, and NKB. FT babies had significantly higher NKB concentrations than PT babies at D7, M2, and M6. MKRN3 and KISS1 concentrations do not differ between FT and PT babies. A strong positive correlation was found between MKRN3 and KISS1 at each time point and in all groups. FSH, LH, TT/E2 concentrations decrease while those of MKRN3 and KISS1 have a trend to increase toward the end of minipuberty. No correlation was detected between gonadotropins and MKRN3, KISS1, NKB concentrations. CONCLUSION: Strong positive correlation demonstrated between KISS1 and MKRN3 suggests that interrelationship between molecules controlling minipuberty is not similar to those at puberty.

Investigation of the biochemical and apoptotic changes in breast cancer cells treated with leaf extract from tea (Camellia sinensis L.) grown with added boric acid.

Tea obtained from the leaves of Camellia sinensis L., a medicinal plant, is a widely popular beverage. Deficiency in boron, a micronutrient for C. sinensis, affects the growth as well as the quality of tea. The aim of this study was to explore whether boric acid at various concentrations added to soil improves the quality of C. sinensis and also whether it changes the apoptotic, anti-proliferative, and anti-oxidative effects of C. sinensis leaf extract on breast cancer (MCF-7) cells. C. sinensis was grown in Rize-Turkey. Boric acid at concentrations of 100 (group B), 300 (group C), and 500 (group D) mg/m2 in sodium tetraborate buffer was administered as a single dose to the soil; group A (no boric acid) was the control. Boron, glutathione (GSH), malondialdehyde and protein carbonyl levels in the C. sinensis leaves were measured. C. sinensis leaf extracts at different concentrations was applied to MCF-7 cells for 24 and 48h. Cytotoxicity, proliferation, and apoptosis were examined. The highest TUNEL+ cell percentage was in MCF-7 cells treated with D group leaf extract compared to the control group (p<0.001 at concentrations of 2.3, 2.6 and 3mg/mL). Moreover, the GSH level increased in the MCF-7 cells under the same conditions (p<0.001 for each concentration). Leaf extracts from C. sinensis grown in soil with boric acid have more anti-proliferative, apoptotic and anti-oxidative effects on the MCF 7 cells.

Investigation the effect of Hypericum perforatum on corneal alkali burns.

Purpose: To investigate the effect of Hypericum perforatum on corneal alkali burn. Methods: We studied 45 250 g weighing, 4 months old Wistar albino rats. Alkaline burns were performed in the corneas of all experimental animals with 2 mol/L NaOH after general anaesthesia. Rats were divided into five groups according to the subsequent process applied to them: group 1 was the topical Hypericum perforatum group, group 2 was the topical pure olive oil group, group 3 was the oral Hypericum perforatum group, group 4 was the oral pure olive oil group, and group 5 was the control untreated group. Rats were sacrificed under general anaesthesia on the 14 day. The rate of corneal inflammation, neovascularization, fibroblastic activity, and cluster of differentiation 31 (CD31) staining was investigated. Result: There were 45 rats at the beginning of the study. One rat in groups 1, 2, and 3 died during the study; therefore, 42 rats could be evaluated. There were 8 rats in group 1, 8 rats in group 2, 8 rats in group 3, and 9 rats in group 4. We found less corneal neovascularization (CNV), inflammation, and fibroblastic activity in group 1 and group 2 than in the other groups (p ˂ 0.001 for all parameters). CNV, inflammation, fibroblastic activity, and CD31 staining rates were lower in group 1 than in group 2 (p ˂ 0.001 for all parameters). There was no difference between groups 3, 4, and 5 (respectively, p = 0.436, 0.634, and 0.750). Conclusions: We found that both topical Hypericum perforatum oily extract and olive oil have anti-inflammatory, anti-angiogenic, and anti-fibroblastic effects when applied after corneal alkali burns in rat corneas. Further studies should be conducted in this field.

Comparison Between Ultrasonography-Guided Popliteal Sciatic Nerve Block and Spinal Anesthesia for Hallux Valgus Repair.

BACKGROUND: We aimed to compare the efficacy, postoperative pain scores, adverse effects, additional analgesic requirements, and patient satisfaction scores of ultrasonography-guided sciatic nerve block by popliteal approach with spinal anesthesia for hallux valgus correction surgery. METHODS: Sixty patients scheduled for hallux valgus correction surgery were enrolled in this prospective randomized study. Unilateral spinal block was performed on patients in the spinal anesthesia group. Popliteal block group patients received popliteal sciatic nerve block with guidance by both nerve stimulator and ultrasonography. Durations of anesthetic and operative interventions and time until the initiation of surgery were recorded for both groups. Pain magnitude of the patients at the 2nd, 4th, 6th, 12th, and 24th hours following anesthetic interventions were assessed with a visual analog scale (VAS). Adverse effects such as postoperative urinary retention and postdural puncture headache were recorded. Also, patient satisfaction was recorded. Patients were interviewed by phone for anesthetic and operative complications at 72 hours postoperatively. RESULTS: Spinal anesthesia group patients exhibited hypotension, bradycardia, postdural puncture headache, and urinary retention rates of 6.6%, 3.3%, 10%, and 3.3%, respectively. Popliteal block group patients showed none of these adverse effects. Moreover, VAS scores of the patients at the 2nd, 4th, 6th, and 12th hours were significantly lower (P < .001, P = .003, P < .001, P <.001, respectively), postoperative first analgesic requirement times were significantly longer (P < .001), and pain satisfaction scores were significantly higher (P < .001) in the popliteal block group. CONCLUSION: Given the complications related to spinal anesthesia and its insufficiency to maintain analgesia postoperatively, we believe the preferred anesthetic method should be peripheral nerve blocks for hallux valgus correction surgeries. LEVEL OF EVIDENCE: Level I, randomized prospective study.

[Incidence of chronic pain after ingunial hernia repair]. / Inguinal herni onarimi sonrasi kronik agri insidansi.

OBJECTIVES: The percentage of chronic pain in adults having inguinal hernia repair is 5-35%. Although this pain is thought to be related to some reasons, there is not an exact conclusion about this. In this study, the aim was to point out the incidence of chronic pain after inguinal hernia repair and determination of the risk factors. METHODS: Two hundred and four patients having inguinal hernia surgery between January 2011 and December 2012 were included into this study. The patients' pain was measured with VAS within 24 hours and at the third and the sixth month after surgery. The patients whose VAS was >3 three months after surgery were evaluated to have chronic pain. RESULTS: The incidence of pain continuing 3 months after surgery was 18.6% and 11.2% six months after surgery. 78.3% of the patients had already had pain before surgery, and in 28% of them, chronic pain had evolved. The measure of VAS within 24 hours postoperatively was found higher in patients who developed chronic pain (3.13 ± 1.12/1.71 ± 1.27). 5.2% of the patients had re-operation for reparation and chronic pain developed in all. Chronic pain was neuropathic in 48% of the patients, and its severity was moderate. CONCLUSION: The incidence of chronic pain after inguinal hernia repair was found %18, compatible with similar studies. Compared with other risk factors, preoperative pain, postoperative severe acute pain and reoperations were thought to be the most important risk factors for the development of chronic pain.

Acute Back Pain Following Surgery under Spinal Anesthesia.

INTRODUCTION: The purpose of this study was to determine the factors having a role in the occurrence of acute back pain following spinal anesthesia. METHODS: Six hundred and forty-nine patients who underwent surgery under spinal anesthesia were enrolled in this prospective observational study. Patients' age, sex, BMI, ASA physical status, educational status, history of back pain, spinal needle radius, spinal interspace level of intervention, method of approach for spinal anesthesia, position during spinal anesthesia, angle of puncture with respect to the spinal ligaments, magnitude of pain during intervention, number of lumbar punctures, number of bony contacts, amount of bupivacaine administered intrathecally, type of surgical procedure, surgical position, duration of the surgery, and duration of anesthesia parameters were recorded. Patients were inquired for existence and magnitude of back pain on the 1st day and the 4th week postoperatively. Multivariate analysis is performed via logistic regression model to parameters that are found to be significant in univariate analysis. RESULTS: Assessment of the data from the postoperative 1st day showed 29.3% of the patients suffered back pain. Postspinal acute back pain was related to the number of bony contacts (P = 0.016), history of back pain (P = 0.0001), spinal needle radius (P = 0.022), and duration of the surgery (P = 0.037). CONCLUSION: Contrary to the common belief, it is demonstrated in this study that number of lumbar punctures, method of approach and position of the spinal anesthesia, age, sex, surgical position, and the type of the surgery did not correlate with occurrence of acute back pain following spinal anesthesia.

Impact of obturator nerve block on the short-term recurrence of superficial bladder tumors on the lateral wall.

PURPOSE: The aim of this study was to compare the recurrence rates of patients with bladder tumors on the lateral wall undergoing transurethral resection of bladder tumor(TUR-BT) with or without obturator nerve block (ONB) and to investigate the impact of ONB on the effective tumor resection on the lateral bladder wall. MATERIALS AND METHODS: All patients who underwent TUR-BT under spinal anesthesia within the three-year study period in the study center were reviewed retrospectively. Among these, 68 patients who had been diagnosed with de novo lateral bladder wall tumor and included in low risk group 1n accord with European Organization for Research and Treatment of Cancer (EORTC) classification, undergone complete resection were enrolled into the study. Group 1 (36 patients who underwent TUR-BT with only spinal anesthesia) and group 2 (32 patients who underwent TUR-BT with spinal anesthesia plus ONB) were evaluated with respect to tumor recurrence rates and disease-free time to recurrence, if any. RESULTS: Follow-up periods (range, 19 to 41 months for group 1 and 19 to 39 months for group 2) and overall recurrence rates (group 1, 27.8% and group 2, 18.8%) were also found to be similar. Mean time to recurrence was significantly higher in group 2 (15 ± 5.5 months) than in group 1 (7.8 ± 4.5 months) (P = .009) CONCLUSION: ONB employed in addition to spinal anesthesia in TUR-BT involving the lateral wall can prolong time to recurrence and increase the chance to lengthen disease-free survival in low-risk superficial bladder tumors.

Metal concentrations in surface sediments of Beyler reservoir (Turkey).

The accumulation of metals (Iron, Aluminium, Zinc, Copper, Manganese, Boron, Chromium, Nickel, Cadmium, Lead) was seasonally (November 2009 to July 2010) measured in sediment samples taken from different areas of Beyler reservoir which is an important water source for irrigation in West Black Sea region (Turkey). Metals in sediment samples were analyzed by ICP-OES. The difference between the stations except for Zn metal (p < 0.05) has not been considered as important and a statistical difference between seasons for Fe, Ni metals (p < 0.01) and Cu metal (p < 0.05) has been observed. The magnitude of metal concentrations in sediment was determined as Aluminium > Iron > Manganese > Zinc > Chromium > Copper > Boron > Nickel > Lead > Cadmium. Enrichment factor (EF) for all metals has been calculated (EF < 1). In the evaluation done by considering the EF values, it is seen that the metal concentrations found in the Beyler Dam Lake sediment stem from the natural composition of the sediment.
