Introduction:
Menopause, defined as the cessation of menstruation for at least 12 months, is one of the important stages of a woman's life cycle. Some hormonal variations occur during the transition to menopause, which affects women’s quality of life. Recently, the role of dietary factors in alleviating symptoms has been investigated.
Aim of this study:
We tried to investigate the relationship between dietary inflammatory index (DII), food-based dietary inflammatory index (FDII) and quality of life, and menopausal symptoms, comparing their predictive power and suggesting the best cut-off point.
Methodology:
149 postmenopausal women were included in the cross-sectional study. After collecting data by interview, the desired variables were calculated. Logistic regression and ROC curves were used to investigate the relationship and predictive power of DII and FDII with menopausal symptoms.
Findings:
We observed that both DII and FDII were significantly associated with the severity of sexual symptoms. The first tertile of DII (OR = 0.252, P-value = 0.002) and FDII (OR = 0.316, P-value = 0.014) had a significantly lower odds ratio for severe to moderate symptoms compared to the third tertile. Both inflammatory indices had significant predictive power in predicting the probability of having severe to moderate poor quality of life (FDII (p-value = 0.004) > DII (p-value = 0.006)) and sexual symptoms (DII (p-value = 0.002) > FDII (p-value = 0.003)). Also, regarding the physical subtype, only FDII (p-value = 0.002) results were significant.
Conclusion
Both dietary inflammatory indices appear to be suitable for predicting quality of life, but FDII had slightly more predictive power. It seems that the quality of life and severity of menopausal symptoms may be improved, particularly with regard to sexual symptoms, by following an anti-inflammatory diet.
Detection of attacks in the Internet of Things with the feature selection approach based on the whale optimization algorithm and learning by majority voting

Published: January 2023

Penetration into the Internet of Things network is a challenge in the security of new-generation networks and smart cities. In most cases, malware is distributed in the Internet of Things and smart objects are infected by malware. Objects infected with malware or viruses, which are called botnets, perform attacks such as DDoS against network services. DDoS attacks make network services inaccessible to users. A suitable approach to detect attacks based on malware and botnet is to use intelligent and distributed intrusion detection systems in the Internet of Things and smart cities. In other research, a centralized architecture and deep learning and machine learning method have been used to design intrusion detection systems. Centralized approaches have limited ability to process large volumes of traffic and are vulnerable to DDoS attacks. In this paper, a distributed intrusion detection system is designed with two stages dimensionality reduction and classification. In the first stage, a new and improved version of the whale optimization algorithm(WOA) has been used to select features and reduce traffic dimensions in fog nodes. In the second stage, each fog node performs the classification of the important features of the network traffic by voting and combined learning. The fog nodes share the IP address of the attacking nodes with the detection of the attacking node. Experiments showed that the improved WOA algorithm has less error in calculating the optimal solution than the optimization algorithm of the WOA algorithm. Reducing the feature selection objective function in the proposed method shows that the WOA algorithm is finding optimal features for intrusion detection and reducing the intrusion detection error. The advantage of the proposed intrusion detection system is to deal with DDoS attacks and cooperation between fog nodes to share blacklists. Tests showed that the proposed method in detecting network intrusion without feature selection has accuracy, sensitivity, and precision of 98.21%, 98.09%, and 97.88%. The proposed method with feature selection has accuracy, sensitivity, and precision of 99.39%, 99.31%, and 99.28%. The accuracy and precision of the proposed method in network intrusion detection are higher than the gray wolf algorithm, genetics and support vector machine, the binary gray wolf algorithm, and the hybridized GWO and GA algorithm. The proposed method is more accurate in intrusion detection than the GWO + PSO and firefly algorithms.

Published: January 2023

Outcomes following human dense connective tissue (DCT) repair are often variable and suboptimal, resulting in compromised function and development of chronic painful degenerative diseases. Moreover, biomarkers and mechanisms that guide good clinical outcomes after DCT injuries are mostly unknown. Here, we characterize the proteomic landscape of DCT repair following human tendon rupture and its association with long-term patient-reported outcome. Moreover, the regulatory mechanisms of relevant biomarkers were assessed partly by gene silencing experiments. A Mass-Spectrometry based proteomic approach quantified a large number (769) of proteins, including 51 differentially expressed proteins among 20 good versus 20 poor outcome patients. A novel biomarker, elongation factor-2 (eEF2) was identified as being strongly prognostic of the 1-year clinical outcome. Further bioinformatic and experimental investigation revealed that eEF2 positively regulated autophagy, cell proliferation and migration, as well as reduced cell death and apoptosis, leading to improved DCT repair and outcomes. Findings of eEF2 as novel prognostic biomarker could pave the way for new targeted treatments to improve healing outcomes after DCT injuries.

Published: January 2023

Background
One of the most common kidney illnesses in developing countries is pediatric nephrotic syndrome (PNS), which is frequently associated with dyslipidemia and edema. The rapid discovery of genes related to NS has aided in the understanding of the molecular mechanics of glomerular filtration. The goal of this study is to determine the relationship between NPHS2 and ACTN4 in PNS youngsters.
Methods
A study with 100 NS children and 100 healthy matched volunteers was conducted. Genomic DNA was extracted from peripheral blood. Single-nucleotide polymorphisms were genotyped using ARMS-PCR.
Results
a substantial decline in the level of albumin was found in NS cases (p < 0.001) Further on, a significantly difference in T.C and TG level between healthy and NS patient. Molecular study showed a highly significant difference of NS patients from controls regarding NPHS2 rs3829795 polymorphic genotypes as the GA heterozygous genotype shows highly significant difference from controls (P < 0.001) as well as GA + AA genotypes (P < 0.001) in comparison with GG genotype. Regarding rs2274625, The GA heterozygous genotype showed no statistically significant difference between genotypes and alleles with NS (p = 0.246). Association of AG haplotype NPHS2 rs3829795-rs2274625 haplotypes found a significant association with the risk of developing NS (p = 0.008). Concerning the ACTN4 rs121908415 SNP, there was no link between this mutation and NS children.
Conclusion
The Correlation of AG haplotype NPHS2 rs3829795-rs2274625 haplotypes identified a strong association with the likelihood of getting NS, according to our findings. There was no connection found between the ACTN4 rs121908415 SNP and NS children.

Authors: Ren Dewang , Wang Zhiyuan , Miao Libin , Lu Weiqiang , Ma Runyang , Dou Xuejun
Published: January 2023

Backgrounds: To explore the clinical features, diagnosis, treatment, and prognosis of intrathoracic pseudomyxoma peritonei.
Methods: A retrospective analysis of the clinical findings pertaining to five intrathoracic pseudomyxoma peritonei patients that underwent surgical treatment at the Aerospace Center Hospital between March 2013 and May 2021 was conducted. All patients underwent thoracic cytoreductive surgery to resect all visible intrathoracic mucinous lesions, followed by regular follow-up to detect postoperative outcomes.
Results: Four patients exhibited evidence of direct extension into the pleural cavity, and three underwent parietal/visceral pleurectomy to remove the mucinous tissue from the thoracic cavity to the greatest degree possible. One patient underwent the resection of disseminated pleural and lung lesions followed by hyperthermic intrathoracic chemotherapy (HITOC). One patient exhibited pulmonary metastases and underwent lobectomy. Macroscopic tumor resection was performed for all patients. Postoperative histopathology results from all five patients revealed a diagnosis of low-grade peritoneal pseudomyxoma arising from the appendix. One patient developed incomplete intestinal obstruction on day 5 post-surgery and was discharged following successful treatment. None of the included patients experienced operative mortality or serious postoperative complications. Patients were monitored for a mean follow-up interval of 22 months, and exhibited 1- and 3-year survival rates of 100% (5/5) and 40% (2/5), respectively.
Conclusion: Intrathoracic pseudomyxoma peritonei is a rare clinical disease associated with a poor prognosis that primarily results following injury to the diaphragm during the surgical treatment of pseudomyxoma peritonei. Cytoreductive surgery to treat thoracic tumors in combination with HITOC can alleviate the symptoms of this condition and can contribute to better prognostic outcomes. However, it is important to remain attentive to the potential for perioperative complications.

Published: January 2023

Purpose Cervical laminoplasty (CLP) is a developed surgical procedure for the treatment of cervical spondylotic myelopathy (CSM), but only a few of those studies focus on preoperative dynamic cervical sagittal alignment and the study of different degrees of loss of cervical lordosis (LCL) is lacking. This study aimed to analyze patients who underwent CLP to investigate the effect of cervical extension and flexion function on different degrees of LCL.
Methods This was a retrospective study of the patients who underwent CLP between January 2019 and December 2020. The cervical lordosis (CL), T1 slope (T1S), cervical sagittal vertical axis (cSVA), CL in flexion (Flex CL), CL in extension (Ext CL), cervical spine range of motion (ROM), cervical spine range of flexion (Flex ROM) and extension (Ext ROM) were measured. The extension ratio (EXR) was defined as 100 × Ext ROM/ROM. LCL was defined as preoperative CL - postoperative CL. Patients were classified into the following three groups according to the LCL: stability group: (LCL ≤ 5°); mild loss group (5° < LCL ≤ 10°); and severe loss group (LCL > 10°). The Japanese Orthopedic Association (JOA) score was used.
Results Seventy-nine patients were enrolled (mean age 62.92 years; 51 men, 28 women) in the study. Among the three groups, cervical extension Ext ROM was the best in the stability group. Compared with the stability group, Flex ROM was significantly higher and the extension ratio (EXR) was significantly lower in the severe loss group. Compared with the severe loss group, JOA recovery rates were better in the stability group. Receiver-operating characteristic curve (ROC) analysis to predict LCL > 10° (area under the curve = 0.808, p < 0.001). The cutoff value for EXR was 16.80%, with sensitivity and specificity of 72.5% and 82.4%, respectively.
Conclusion CLP should be carefully considered for patients with a preoperative low Ext ROM and high Flex ROM, as a significant kyphotic change is likely to develop after surgery. EXR is a useful and simple index to predict significant kyphotic changes.

Published: January 2023

Colloidal InAs quantum dots (QDs) are emerging candidates for NIR-SWIR optoelectronic applications because of their excellent electrical and optical properties. However, the synthesis of InAs QDs, which demands a strongly reducing atmosphere or highly reactive precursors, is difficult because of their strong covalent bonding nature and lack of group 15 precursors. While the co-reduction method with commercially available arsenic precursors enables the facile synthesis of InAs QDs, it causes a broad size distribution, requiring a subsequent size-selection process. In this study, we introduce zinc metal ions in the form of a coordination complex during the co-reduction reaction of indium and arsenic precursors. Zn ions can chemically passivate the surface of InAs QDs, allowing the promotion of size focusing and removal of surface defects. When the InAs QDs are integrated into infrared photodiodes as IR absorbers, the surface-attached Zn ions can electrically modulate the energy level and carrier concentration. The infrared photodiodes with InAs:Zn QD layers exhibit two orders of magnitude lower dark current and about twice faster photo-response than those using bare InAs QDs.

Published: January 2023

Twoazole-based Schiff bases, namely 2-(((1H-1,2,4-triazol-3-yl)imino)methyl)-4-bromophenol, TIB, and 4-Bromo-2-((thiazol-2-ylimino)methyl)phenol, BTP, were synthesized and applied as corrosion inhibitors for mild steel, MS, in 0.5 M hydrochloric acid medium based on investigations with weight loss, potentiodynamic polarization, and electrochemical impedance measurements. Electrochemical impedance study showed that in the presence of TIB and BTPthe corrosion of MS in acidic medium was reduced significantly through a charge transfer mechanism. Tafel polarization revealed that the TIB and BTP behaved as mixed-type inhibitors, predominantly of cathodic type. The MS surface has been blocked by inhibition action of TIB and BTP molecules following Langmuir adsorption isotherm. The formed protective layer on MS surface was verified using scanning electron microscopy (SEM) and X-ray spectroscopy (EDX) techniques. Furthermore, atomic force microscopic (AFM) study revealed that the current inhibitors increase the surface smoothness of AFM micrographs by adsorbing on the metallic surface. Experimental results declared that the optimum concentration of TIB and BTP for coverage of MS surface are 600 µM and 400 µM, respectively. In addition, TIB is a more effective corrosion inhibitor than BTPfor MS in 0.5 M HCl medium. Furthermore, atomic force microscopic (AFM) study revealed that the current inhibitors increase the surface smoothness of AFM micrographs by adsorbing on the metallic surface.

Water molecules near cellulose nanocrystals (CNCs; produced via sulfuric acid-catalyzed hydrolysis) are believed to relax slower than those in the bulk liquid, which may result in unique properties of CNC aqueous dispersions. This study analyzed the polarization behavior of water molecules in CNC aqueous dispersions and other reference samples using a dielectric relaxation spectroscopy (DRS) technique in the microwave frequency range (200 MHz – 20 GHz). As the CNC concentration increases, two slow relaxation components become prominent. The comparison with DRS data of aqueous dispersions of nanoporous silica, polyvinyl alcohol (PVA), and hairy CNCs with amorphous chains in both ends suggested that these slow relaxation modes of water near CNC surfaces cannot be attributed to direct hydrogen bonding interactions with the hydroxyl (OH) groups exposed and immobilized at the solid surface. Instead, they are rather similar to the water molecules interacting with OH groups attached to flexible polymer chains. Molecular dynamics (MD) simulations of the polarization behavior of water near the (110) facet of cellulose Ib crystals confirmed that the interactions of water molecules with the cellulose crystal surface do not cause slower relaxations in the frequency range studied via the DRS. These results indicated that the CNC surface cannot be depicted with the crystallographic facets of cellulose Iβ; instead, it resembles a polymer-brush surface on which the short glucan residues or fragments of the strong acid-catalyzed hydrolysis process are swollen and extended into the aqueous phase.

Published: January 2023

The aim of this study is to evaluate the association of perinephric fat volume (PNFV) and the Mayo Adhesive Probability (MAP) score with time to clamping (TTC) in robot-assisted partial nephrectomy (RAPN). The study subjects consisted of 73 tumors in 72 patients who underwent trans-peritoneal RAPN at a single cancer center between February 2020 and July 2022. Clinical characteristics including R.E.N.A.L. Nephrometry score, MAP score and PNFV were evaluated in a multivariate analysis in relation to TTC, which was classified into two groups based on median TTC. MAP score and PNFV were analyzed separately. PNFVs were measured by SYNAPSE VINCENT® by a single expert urologist. Median TTC was 67 (range: 36-119) minutes. Spearman’s rank correlation analysis indicated that a significant correlation was observed between PNFV and MAP score with a value of 0.81 (p < 0.0001). Univariate analysis revealed that R.E.N.A.L. nephrometry score ≥7 (p = 0.036), posterior tumor location (p = 0.033), Map score ≥3 (p = 0.02) and PNFV ≥250ml (p = 0.02) were significant factors for prolonged TTC. In a multivariate analysis including PNFV (analysis 1), R.E.N.A.L. nephrometry score ≥7 (OR 3.54, p = 0.018) and PNFV ≥250cm3 (OR 3.94, p = 0.010) were independent factors for prolonged TTC. Similarly for MAP score (analysis 2), R.E.N.A.L. nephrometry score ≥7 (OR 3.54, p = 0.018) and Map score ≥3 (OR 3.94, p = 0.010) were independent factors for prolonged TTC. Both MAP score and PNFV may have a significant impact on TTC.
Experimental investigation of blade tip vortex behavior in the wake of asymmetric rotors
Authors: Abraham Aliza , Leweke Thomas
Published: January 2023

Wakes behind rotors such as wind turbines, propellers, and helicopters can have detrimental effects on downstream structures including increased structural loading. These wakes are characterized by helical vortices shed from the blade tips, which are subject to instabilities that cause the vortices to break down, reducing the strength of the wake. One type of instability, vortex pairing, can be triggered by introducing a slight asymmetry to the rotor. The current study investigates the effectiveness of different types of rotor asymmetries at triggering the pairing instability through an experimental campaign involving 14 rotor configurations. The leapfrogging distance, or the point where adjacent vortex loops swap positions, is used as a metric to compare the different types of asymmetries. For all cases tested, leapfrogging occurs between 4.1 and 1.8 rotor radii downstream of the rotor for the baseline and most perturbed configurations, respectively. Even a small perturbation of 6% of the vortex spacing reduces the leapfrogging distance by 25% relative to the baseline configuration. Some of the most interesting similarities and differences between cases are discussed in more detail, including the analogy between azimuthal and axial displacements, the importance of perturbation direction, and the effects of blade devices such as winglets and fins on the vortex system. The findings of the current study can be used to design rotors that passively accelerate wake recovery, mitigating detrimental effects on downstream structures.
On the effect of maintaining a fixed ambient temperature in the analysis of a photovoltaic device's performance
Authors: Frenkel Ido , Niv Avi
Published: January 2023

This article studies the consequence of shifting the point of view of photovoltaic system analysis from having a constant temperature to having a constant temperature of its ambient environment. To do so, we derive the power balance of the photovoltaic system—the rate equivalent of the first law of thermodynamics. We solve this equation in conjunction with the detailed balance photon rate equation to find the current and the temperature as a function of the cell's potential for a given bandgap, sources (sun and sky), ambient temperature, and heat conduction coefficient. We find the model to give the expected behavior of a photovoltaic system close to standard conditions. However, we find that the expected rise in efficiency for moderate concentration may flip to reduction if the cell’s ability to dissipate heat is not exquisite. Our model's applicability to any photovoltaic device is demonstrated by analyzing a thermoradiative cell—the inverse of a solar cell. We show compatibility with known models and the flexibility at which less-than-ideal systems can be analyzed in our approach. We believe that centering the analysis on a fixed ambient temperature is a more faithful representation of photovoltaic systems' experimental and real-life conditions. As such, it is essential for the development of photovoltaic technology. Also, this shift in point of view raises some fundamental questions regarding the energy carried by the electrical current that may prove vital for developing future photovoltaic concepts.

Published: January 2023

Light scattering, whether caused by desired or spurious elements, is considered one of the main phenomena that present great challenges for the nonlinear (NL) optical characterization of turbid media. The most relevant disturbing factor is the random deformation suffered by the spatial intensity distribution of the laser beam due to multiple scattering. In this work, we report the IC-scan (intensity correlation scan) technique as a new tool to characterize the NL optical response of scattering media, by taking advantage of light scattering to generate speckle patterns sensitive to wavefront changes induced by the self-focusing and self-defocusing effects. Peak-to-valley transmittance curves, with a higher signal-to-noise ratio, are obtained by analyzing the spatial intensity correlation functions of the different speckle patterns, even in very turbid media where conventional NL spectroscopy techniques fail. To demonstrate the potential of the IC-scan technique, the NL characterization of colloids that contain a high concentration of silica nanospheres as scatterers, as well as gold nanorods, which act as NL particles and light scatterers, was performed. The results show that the IC-scan technique is more accurate, precise and robust to measure NL refractive indices in turbid media, overcoming limitations imposed by well-established Z-scan and D4σ techniques.

Objective

There is hardly any information on the consumption of healthcare resources by older people with differentiated thyroid cancer (DTC). We analyzed these consumptions in older patients with DTC and compared patients 75 years and older with subjects aged 60–74 years.

Methods

A multicenter, retrospective analysis was designed. We recorded three groups of health resources consumption (visits, diagnostic procedures, and therapeutic procedures) and identified a subgroup of patients with high consumption of resources. We compared elderly patients (group 1, 60–74 years) with very old patients (group 2, ≥ 75 years).

Results

We included 1654 patients (women, 74.4%), of whom 1388 (83.9%) belonged to group 1 and 266 (16.1%) to group 2. In group 2, we found a higher proportion of patients requiring emergency department visits (7.89% vs 4.32%, P < 0.05) and imaging studies (24.1% vs. 17.3%; P < 0.05) compared to group 1. However, we did not find any significant difference between both groups in the consumption of other visits, diagnostic procedures, or therapeutic procedures. Overall, 340 patients (20.6%) were identified as high consumers of health resources, 270 (19.5%) in group 1 and 70 (26.3%) in group 2 (P < 0.05). Multivariate logistic regression analysis showed that the risk of recurrence and mortality, radioiodine treatment, tumor size, and vascular invasion were significantly related to the high global consumption of resources. However, the age was not significantly related to it.

Conclusion

In patients with DTC over 60 years of age, advanced age is not an independent determining factor in the consumption of health resources.
Electrospun ZnO-SnO2 Heterojunction Belts for Hydrogen Sensing
Authors: Bulemo Peresi Majura
Published: January 2023

Chemiresistive sensors are promising devices for H2 sensing in a broad range of applications including fuel cells, hydrogen storage systems, petroleum refinement, and diagnosis of oil-insulated transformers. Herein, electrospun ZnO-SnO2 belts were synthesized and applied as resistive-type sensing layers for H2 sensing. The ZnO-SnO2 belts containing 20 mol% of Zn relative to Sn showed a response (Ra/Rg) of 6.7, fast response speed (3.6 sec), and a distinguishable selectivity toward 5 ppm H2 at 400°C in the presence of HCHO, CH4, NH3, CO, and CO2. The sensor displayed a repeatable response when subjected to 15 cycles of alternate air and 5 ppm H2 exposure. A unique H2 sensing performance of the belts was attributed to their belt morphology, numerous surface pores, smaller crystal size, ZnO/SnO2 heterojunction, and ZnO metallization following H2 exposure.

Published: January 2023

Background:
Robotic-assisted appendectomies and cholecystectomies are believed to increase cost compared to the gold standard laparoscopic approach. Two equally qualified surgeons performed both approaches over two years to evaluate intraoperative duration, time to discharge, conversion to open procedure, and readmission within 30 days.
Findings:
110 laparoscopic, 81 robotic-assisted appendectomies; and 105 laparoscopic and 165 robotic-assisted cholecystectomies were performed. Intraoperative time; laparoscopic appendectomy was 1.402 vs 1.3615 hours for robotic-assisted (P-value = 0.304); laparoscopic cholecystectomy was 1.692 vs 1.634 hours for robotic-assisted (P-value = 0.196). Time to discharge, was 38.26 for laparoscopic vs 28.349 hours for robotic-assisted appendectomy (P-value = 0.010), and 35.95 for laparoscopic vs 28.46 hours for robotic-assisted cholecystectomy (P-value = 0.002). Intraoperative conversion to open; only laparoscopic procedures were converted, one appendectomy and nine cholecystectomies. None in the robotic-assisted procedures. Readmissions, none in the appendectomy group and three in the cholecystectomy group. One laparoscopic and two robotic-assisted cholecystectomy patients were readmitted.
Conclusion:
Intraoperative times for robotic appendectomy and cholecystectomy were not longer than laparoscopic approach. Robotic approach shortened the time to discharge and the likelihood for conversion to open procedure.
Mindfulness in the Digital Workplace: an explorative study of the compatibility of mindfulness and technology
Authors: Wrede Sammy J.S. , Esch Tobias , Michaelsen Maren M.
Published: January 2023

Mindfulness has made its way into the business context. Simultaneously, several options for digitally encouraging mindfulness have been proposed in recent years, with opposing opinions questioning the compatibility of mindfulness and technology, claiming it is a paradox. This study aims to examine the compatibility of mindfulness and technology, i.e., how mindfulness and digitalization interact as compatible or incongruous phenomena in the digital working context. Semistructured interviews with 15 experts, all specializing in technology and mindfulness in the workplace, were conducted to generate hypotheses of digital mindfulness at work. Qualitative content analysis as well as content analysis via extraction were utilized in this study to explore mutual relationships. Information about workplace mindfulness, digitalization, technology and digital stress was synthesized. The themes “Mindful by Workplace-Design” (a) and “Working Mindfully in a Digital Cooperation” (b) resulted in suggested modifications for digital workplaces. The compatibility of the two phenomena escalated at the “Tipping Point” (c), reached beyond the use of mindfulness apps, i.e., when wearables are added. The results point out the limits of digital mindfulness, as well as opportunities for the cooperation of mindfulness and technology. For employers, the study provides guidance for shaping mindful digital workplaces and mindful work cultures.

Authors: Fusté-Forné Francesc , Leer Jonatan
Published: January 2023

While relationships between food and tourism have been extensively investigated in recent decades, the Faroe Islands is a lesser studied food destination. This article analyses the specificities of restaurant scene in the context of food tourism in Tórshavn, the capital of the Faroe Islands, based on the official promotion of the dining landscape. The authors specifically discuss how the remote Arctic destination of Tórshavn positions itself as a culinary destination based on concepts of authenticity, exoticism, sustainability and innovation. Results show that the small and isolated capital of Tórshavn balances the exoticism of traditional Faroese food experiences with more generic international flavors and urban spaces. Hence, the case opens interesting perspectives on the negotiations of the local and the global in contemporary food tourism marketing of remote island destinations.

Green gram (Vignaradiata L.) is one of Indias most essential and widely cultivated pulse crops. Several biotic and abiotic factors cause the yield loss in green gram. Among the biotic factors, root rot is one of the devasting factors which can cause maximum yield loss under severe conditions. Ten pathogenic isolates of Macrophominaphaseolinacausing root rot in Greengramwere collected from different locations in the Perambalur District of Tamil Nadu. The isolates produced root rot symptoms under artificial inoculation to confirm the pathogenicity. Among these isolates, Macrophominaphaseolina 1 isolated from Valikandapuramwas virulent, which took for further study. To test the efficacy of fungal biocontrol agents against the Greengram root rot pathogen, ten Trichodermaviride were isolated from ten different places in the Perambalur District of Tamil Nadu and evaluated in vitro. Among the ten isolates tested against Macrophominaphaseolina, the isolate Tv- 1 isolated from the Esanai village of Perambalur District effectively arrested the mycelial growth of Macrophominaphaseolina, which recorded 61.00 per cent growth inhibition over control.

Supernumerary kidneys are very rare renal malformations, little described in the literature. Its diagnosis is difficult, most often discovered during a radiological exploration either fortuitously or during a complication. We report a case of bilateral supernumerary kidneys on fused crossed ectopia of the right kidney diagnosed by ultrasound and computed tomography in Bamako in a 16-year-old girl. The objective of this work is to provide the place of imaging in the diagnostic management of supernumerary kidneys.

Fermentation is one of the necessary processes in the production of bioethanol. Reducing sugar from cellulose will convert it into bioethanol with microorganisms as catalysts. Microorganisms used in bioethanol production also need to be considered and adjusted to the selection of the fermentation process. A previous study examined bioethanol production. However, many still get relatively low yields and require a long time of fermentation to produce bioethanol. Also continuously developing to obtain bioethanol with high yield. The fermentation process included Separate Hydrolysis Fermentation (SHF), Simultaneous Saccharification and Fermentation (SSF), and Consolidated BioProcessing (CBP). The fermentation process has its respective advantages and disadvantages, mainly when applied to lignocellulosic-containing materials. This review will explain and develop future trends in each method.

The demand of water is increasing day by day because of population explosion and rapid urbanisation. In this regard, desalination is one of the prominent technologies for providing potable water from saline aqueous media. Among available methods of desalination, seawater reverse osmosis is commercially viable and practiced in many countries of the world. But high energy use is one of the drawbacks of reverse osmosis process. Hence, this study aimed to analyse flow energy of reverse osmosis unit in seawater desalination plant with energy recovery device. A conventional material and energy balances is applied for the analysis. From the analysis, zero loss is observed in recirculation pump and significant loss of 66.65 kJ/s is estimated in energy recovery device. It could be concluded that energy recovery device is a suitable option to reduce the energy use in reverse osmosis unit.

Study Design: Descriptive cross-sectional study. Place and Duration of Study: Department of Obstetrics and Gynaecology, CAIMS, Karimnagar from October 2020 to April 2022. Material and Methods: This descriptive cross-sectional study included women of any parity and age >45 years who had spontaneous cessation of menstruation for the last one year and who presented with abnormal uterine bleeding. Premenopausal women, drug or irradiation induced, or iatrogenic menopause cases were excluded. All patients were admitted, transvaginal ultrasound done (cut off endometrial thickness >4mm) and subjected to dilatation and curettage under anesthesia and endometrial biopsies obtained. Samples were sent for histopathology and followed. Results: A total of 70 women were included. Commonest age group was 61-70 years, and was seen in 38 (54.3%) women, followed by the 52-60 years age group where 18 (25.7%) subjects were observed. Mean age was 62 Â± 2.54 years. Twenty-four (35%) women were hypertensive while Type 2 Diabetes Mellitus (T2DM) was seen in 14 (20%). forty (57%) women complained of streaks of blood on the sanitary pad, and in 56 (80%) (P=0.032) there were recurrent episodes. Forty-eight (68.57%) women were multiparous. Atrophic endometrium was the most common benign histopathological pattern, seen in 18 (26%) followed by 16 (23%) chronic endometritis. Endometrial carcinoma was seen in 16 (23%).

Somali ostrich has recently been published as distinct species. The bird is undergoing a drastic decline in population and thus classified as Vulnerable by IUCN. Its conservation demands an urgent understanding of the scope and the severity of the prevailing threats. The decline in range is an important threat to survival and propagation of wild populations in Samburu landscape. We aimed at identifying critical ranges and habitats utilized by the species by investigating its distribution and habitat association within Meibei and West Gate Conservancies, and Samburu National Reserve. Global Positioning System (GPS) coordinates and habitats types were recorded for all ostrich sightings during surveys conducted along predetermined routes in the study area. The Normalized difference vegetation Index (NDVI) at ostrich sighting points were obtained and regressed with the frequency of ostrich observations and the resultant regression models used to generate a spatial distribution model map. Somali ostriches were found to prefer bushy areas to open grasslands. However, they avoided think vegetation probably for predator avoidance. Majority of ostrich coexist with Samburu pastoralists and their livestock. This overlap suggests that any meaningful Somali ostrich conservation planning should focus on the involvement of the Samburu pastoral communities in land use planning.
