RESUMEN

The study focused on the extraction of free erythromycin from commercially manufactured tablets and the use of metal salts to synthesize erythromycin-metal complexes, specifically involving silver (Ag), nickel (Ni), cobalt (Co), and copper (Cu). The synthesis was confirmed through various methods, including elemental analysis, thermogravimetric analysis, Fourier-transform infrared (FTIR), and UV-visible spectroscopy. The microbiological investigation involved Salmonella typhi, Escherichia coli, Staphylococcus aureus, Bacillus cereus, Candida albicans, and Microsporum canis as test organisms. The NCCLS broth microdilution reference method was used to determine the minimum fungicidal concentration and minimum inhibitory concentration of the complexes. The synthesized complexes were highly effective against a variety of fungi and bacteria, with compound Ery-Cu having MIC as low as 1.56 mg/mL, Ery-Cu and Ery-Ni with MBCs of 6.25 mg/mL and Ery-Cu having MFC of 6.25 mg/mL. Dose-dependent inhibitory effects were found upon examination of the antimicrobial susceptibility of specific complexes (Cu, Ni, Co and Ag) at varying concentrations of 100, 50, 25 and 12.5 mm/mL. Antibiotic susceptibility testing revealed efficacy against the tested pathogens. The study suggests that the synthesis of erythromycin-metal complexes, coupled with their antibacterial effectiveness against a diverse spectrum of bacteria and fungi, as they showed promising inhibitory properties when tested against a range of test species (Bacillus cereus, Staphylococcus aureus, Escherichia coli, Salmonella typhi, Candida albicans, and Microsporum canis), could lead to the development of innovative antibacterial agents. Molecular docking simulations were used to examine the interactions between metal complexes with proteins filamentous temperature-sensitive protein Z and lanosterol 14α-demethylase. The study highlights the need for further exploration in pharmaceutical research.

RESUMEN

INTRODUCTION: Vagal nerve stimulator (VNS) implantation is a vital therapy for epilepsy refractory to other treatments; however, it is associated with a very high rate of voice changes. Relatively few of these patients are evaluated for vocal fold motion impairments. In this series, we evaluate 5 such patients with a novel phenotype of forced abduction with VNS stimulation. METHODS: Retrospective case series. RESULTS: Five patients with a VNS implant who underwent operative direct or in-office rigid laryngoscopy and had vocal fold motion impairment associated with VNS activation are included. All 5 patients had vocal fold mobility with VNS off and a fixed with activation. All patients exhibited vocal fold abduction with VNS activation. Patient 2 has since undergone laryngeal reinnervation, which helped her intermittent dysphonia but left a small glottic gap. A type 1 thyroplasty corrected this gap and improved her voice further. Patient 3 has undergone laryngeal reinnervation for which early results show improvement in perceptual and patient reported outcomes. Patients 4 and 5 have both undergone laryngeal reinnervation with improvement in voice. CONCLUSION: Previous reported cases of stimulated immobility associated with VNS use describe only adduction of the vocal fold. This series expands the previous work showing the VNS activation can also cause stimulated immobility in an abducted position, for which reinnervation and other medialization procedures offer promising treatment.

RESUMEN

The current research is related to the synthesis of different concentrations (0, 3, and 7 wt %) Zn doped TiO2-NPs by using the coprecipitation method. The rutile, anatase crystal structure appeared on different diffracted peaks in TiO2-NPs, and the crystallite size (12 to 24 nm) was calculated by using XRD analysis. The spherical, irregular, porous grain-like surface morphology was observed by SEM analysis, and the identification of different functional modes such as hydroxyl, -C-O, -C-O-C, and Ti-O-Ti attached on the surface of the spectrum was examined via FTIR analysis. After that, the increased absorbance of TiO2-NPs by increasing the Zn concentration in TiO2-NPs was observed by UV-visible analysis. After that, the well diffusion method was performed to measure antibacterial activity, and the MTT assay was used to investigate anticancer activity against the HepG2 cell line. It was observed that the inhibition zone of S. aureus and E. coli increased by increasing the concentration of Zn-doped TiO2-NPs from 2 to 32 mm. The 7 wt % Zn-doped TiO2-NPs provided significant anticancer activity against the liver cancer cell line and antibacterial activity. In the future, Zn doped TiO2-NPs can be used for in vitro analysis against different microbial and animal models for the treatment of cancer.

RESUMEN

First time compared the different metals doped ZnS nanoparticles for antibacterial and liver cancer cell line. In this study, copper, aluminum and nickel doped ZnS NPs were synthesized via co-precipitation method. The XRD analysis was confirmed the presence of cubic crystal structure and crystallite size decreased from 6 to 3 nm with doping elements. While as SEM micro-grains were revealed slightly irregular and agglomerated morphology with the presence of dopant elements. The presence of different dopant elements such as Cu, Al and Ni in ZnS NPs was identified via EDX analysis. The FTIR results demonstrate various vibrational stretching and bending modes attached to the surface of ZnS nanomaterials. After that the well diffusion method was used to conduct in-vitro bioassays for evaluation of antibacterial and anticancer activities against E.coli and B.cereus, as well as HepG2 liver cancer cell line. Our findings unveil exceptional results with maximum inhibition zone of approximately 9 to 23 mm observed against E.coli and 12 to 27 mm against B.cereus, respectively. In addition, the significant reduction in cell viability was achieved against the HepG2 liver cancer cell line. These favorable results highlight the potential of Ni doped ZnS NPs for various biomedical applications. In future, the doped ZnS nanomaterials will be suitable for hyperthermia therapy and wound healing process.

RESUMEN

Background and Objectives: Differentiation between brucella spondylodiscitis and Modic type I changes (MC1) includes difficulties. Hematological inflammatory indices (HII) such as neutrophil to lymphocyte ratio (NLR) and aggregate index of systemic inflammation (AISI) are suggested as indicators of inflammation and infection and have diagnostic, prognostic, and predictive roles in various diseases. This study aimed to evaluate differences between brucella spondylodiscitis and MC1 in terms of HII. Materials and Methods: Thirty-five patients with brucella spondylodiscitis and thirty-seven with MC1 were enrolled in the study. Brucella spondylodiscitis and MC1 were diagnosed by microbiological, serological, and radiological diagnostic tools. HII (NLR, MLR, PLR, NLPR, SII, SIRI, AISI) were derived from baseline complete blood count. Results: The two groups were similar for age (p = 0.579) and gender (p = 0.092), leukocyte (p = 0.127), neutrophil (p = 0.366), lymphocyte (p = 0.090), and monocyte (p = 0.756) scores. The Brucella spondylodiscitis group had significantly lower pain duration (p < 0.001), higher CRP and ESR levels (p < 0.001), and lower platelet count (p = 0.047) than the MC1 group. The two groups had similarity in terms of HII: NLR (p = 0.553), MLR (p = 0.294), PLR (p = 0.772), NLPR (p = 0.115), SII (p = 0.798), SIRI (p = 0.447), and AISI (p = 0.248). Conclusions: Increased HII can be used to differentiate infectious and non-infectious conditions, but this may be invalid in brucellosis. However, pain duration, CRP and ESR levels, and platelet count may be useful to distinguish brucella spondylodiscitis from MC1.

RESUMEN

The aim of this study is to evaluate the risk factors for empty follicle syndrome (EFS) in patients with diminished ovarian reserve (DOR) undergoing an intracytoplasmic sperm injection cycle. In this retrospective study, patients with DOR were divided into 2 groups according to the presence of empty follicles on the day of oocyte retrieval. Patient age, body mass index (BMI), anti-Müllerian hormone (AMH), baseline follicle stimulating hormone (FSH) and estradiol (E2) levels, basal antral follicle count (AFC), total gonadotropin dose, and day of stimulation were recorded as risk factors. The association between EFS and these variables was assessed using the logistic regression method and ROC curve analysis. Increased BMI, low AMH, higher baseline FSH, low baseline AFC, higher gonadotropin dose, and longer day of ovulation induction were independent risk factors for EFS in patients with DOR. ROC curve analysis showed that BMI, AMH, baseline FSH, baseline AFC, higher gonadotropin dose, and longer ovulation induction days were predictive parameters in this group. According to the current study, higher BMI, lower AMH, higher baseline FSH, lower baseline AFC, higher gonadotropin dose and longer ovulation induction days were independent risk factors for EFS in patients with reduced ovarian reserve.

RESUMEN

The aim of this study is to evaluate the effects of obesity on clinical outcomes in diminished ovarian reserve (DOR) patients undergoing intracytoplasmic sperm injection cycles. In this retrospective observational cross-sectional study, women admitted to current clinic with DOR undergoing intracytoplasmic sperm injection were divided into 2 groups according to the obesity. Patient age, body mass index, anti-mullerian hormone, baseline follicle stimulating hormone and baseline estradiol levels, antral follicle count, total gonadotropin dose, day of stimulation, number of mature (MII) oocytes, and clinical pregnancy were evaluated. There were no statistically significant differences between groups in terms of age, anti-mullerian hormone, baseline follicle stimulating hormone, baseline estradiol levels, antral follicle count, and clinical pregnancy (P > .05). Total gonadotropin dose, the days of ovarian stimulation were higher and number of MII oocyte were less in the obese group (P < .05). Logistic regression analyses also revealed that the days of ovarian stimulation and number of MII oocyte were significant factors in the study group. ROC curve analysis showed obesity is a negatively affecting factor in DOR patients. Obesity causes more gonadotropin dose longer days of stimulation, and less number of MII oocyte. However clinical pregnancy rate is not negatively affected by obesity according to the current study.

RESUMEN

This study focuses on standardizing sampling techniques and comparing various methods of sample allocation to effectively estimate apple area and production in the Himalayan region of India. We investigate different stratification tools,in formulating a sampling plan using information gathered from select orchardists in the locale during the 2016-17 period, it becomes essential to explore diverse methodologies to define the most suitable stratum boundaries, ascertain the requisite number of strata, and identify the optimal sample size. The stratification process, underpinned by the "Area under Apple" variable, which demonstrates a pronounced association with apple production, assumes a central role in this endeavor Several methods are utilized to construct strata, such as equalizing strata totals, cumulative equalization, equalization of ½{r(x) + f(x)} and equalization of f ( x ) . We assess their efficiencies in estimating total apple production in the study district. The combination of the "Cum f ( x ) " of Neyman allocation demonstrates the lowest variance and the highest efficiency within a range of 2-4 strata, coupled with an increase in sample size from 10 to 40. Consequently, it can be inferred that the "Cum f ( x ) " method, particularly with L > 2, is preferable for estimating apple production in the Himalayan region of India.

RESUMEN

This paper develops an outsourcing collaboration model from a firm's perspective operating in a developing economy. The model considers that producers of the final goods residing in a developed country, and operators of manufacturing plants in a developing country collaborate with each other. The final goods producer supplies headquarter services for the production of intermediate goods in the developing country. The operators of manufacturing plants also supply their services in the domestic economy. This arrangement leads to foreign outsourcing collaborations (FOC) between firms of developed country and developing country. The operators of manufacturing plant maximize revenue subject to the cost constraint. The first order conditions suggests that an increase in wages of skilled labor, price of domestic inputs, and cost of production deter FOC. On the other hand, an increase in demand for and price of foreign headquarter services increases the FOC. Empirical analysis based on data collected from 217 clothing (textile and apparel) firms in the city of Faisalabad (Pakistan) reveals that an increase in wage to labor-productivity ratio reduces FOC. An improvement in skilled of the labor and foreign headquarter services give rise to FOC, whereas an increase in economies-of-scope enhances FOC. Additionally, an inverted U-shaped relationship is found between the cost of production and FOC, which shows that at the initial stage, the firm's cost of production increases with an increase in the level of FOC, but soon after the tipping point, the firm's cost starts decreasing with a further increase in FOC.

RESUMEN

OBJECTIVE: Responsive neurostimulation (RNS) is a US FDA-approved form of neuromodulation to treat patients with focal-onset drug-resistant epilepsy (DRE) who are ineligible for or whose condition is refractory to resection. However, the FDA approval only extends to use in patients with one or two epileptogenic foci. Recent literature has shown possible efficacy of thalamic RNS in patients with Lennox-Gastaut syndrome and multifocal epilepsy. The authors hypothesized that RNS of thalamic nuclei may be effective in seizure reduction for patients with multifocal or regionalized-onset DRE. METHODS: The authors performed a retrospective chart review of all patients who had an RNS device managed at Texas Children's Hospital between July 2016 and September 2023, with at least one active electrode in the thalamic nuclei and ≥ 12 months of postimplantation follow-up. Information conveyed by the patient or their caregiver provided data on the change in the clinical seizure frequency, quality of life (QOL), and seizure severity between the preimplantation baseline visit and the last office visit (LOV). RESULTS: Thirteen patients (ages 8-24 years) were identified with active RNS leads in thalamic nuclei (11 centromedian and 2 anterior nucleus). At LOV, 46% of patients reported 50%-100% clinical seizure reduction (classified as responders), 15% reported 25%-49% reduction, and 38% reported < 25% reduction or no change. Additionally, 42% of patients reported subjective improvement in QOL and 58% reported improved seizure severity. Patients with focal cortical dysplasia (FCD) responded strongly: 3 of 5 (60%) reported ≥ 80% reduction in seizure burden and improvement in seizure severity and QOL. Patients with multifocal epilepsy and bilateral thalamocortical leads also did well, with all 3 reporting ≥ 50% reduction in seizures. CONCLUSIONS: RNS of thalamic nuclei shows promising results in reducing seizure burden for patients with multifocal or regional-onset DRE, particularly in a bilateral thalamocortical configuration or when addressing an underlying FCD.

RESUMEN

Establishing sustainable communities requires bridging the gap between academic knowledge and societal requirements; this is where entrepreneurial education comes in. The first phase involved a comprehensive review of the literature and extensive consultation with experts to identify and shortlist the components of entrepreneurship education that support sustainable communities. The second phase involved Total Interpretative Structural Modelling to explore or ascertain how the elements interacted between sustainable communities and entrepreneurial education. The factors are ranked and categorized using the Matrice d'impacts croises multiplication appliquee an un classement (MICMAC) approach. The MICMAC analysis classifies partnerships and incubators as critical drivers, identifying Student Entrepreneurship Clubs and Sustainability Research Centers as dependent elements. The study emphasizes alumni networks and curriculum designs as key motivators. The results highlight the critical role that well-designed entrepreneurial education plays in developing socially conscious entrepreneurs, strengthening communities, and generating long-term job prospects. The study provides a valuable road map for stakeholders dedicated to long-term community development agendas by informing the creation of strategic initiatives, curriculum updates, and policies incorporating entrepreneurial education.

RESUMEN

Two-dimensional (2D) materials such as MXenes have attracted considerable attention owing to their enormous potential for structural flexibility. Here, we prepared a Mo2TiC2Tx-layered structure from parent Mo2TiAlC2Tx MAX by chemically selective etching of the aluminum layer. The prepared MXene was employed in composite formation with CTAB-grafted multiwalled carbon nanotubes (MWCNTs) to have a structure with improved electrochemical performance. The samples were characterized to analyze the structure, morphology, elemental detection, vibrational modes, and surface chemistry, followed by an electrochemical performance of the Mo2TiC2Tx MXene and MWCNTs@Mo2TiC2Tx composite using the GAMRAY Potentiostat under a 1 M KOH electrolyte. The specific capacitance of pristine Mo2TiC2Tx was 425 F g-1, which was enhanced to 1740 F g-1 (almost 4 times) at 5 mV s-1 due to the increase in active surface area and conductive paths between the MXene sheets. The charge storage mechanism was studied by further resolving the cyclic voltammograms. MWCNTs@Mo2TiC2Tx showed much improved electrochemical performance and reaction kinetics, making it an ideal material candidate for supercapacitor applications.

RESUMEN

BACKGROUND:  Laparoscopic cholecystectomy (LC) is the preferred method for gallstone removal, but bile duct injuries remain a concern. Achieving the critical view of safety (CVS) is pivotal in preventing such injuries. The aim of this study was to compare the rates of difficult LC in those with CVS achieved compared to those with CVS not achieved. METHODS: We performed a single-center prospective study on all patients with ultrasound-confirmed symptomatic gallstones. Patients were excluded if they refused to consent or if they underwent LC for indications other than gallstone disease. Patients were stratified into two groups as CVS not achieved and CVS achieved groups and compared for outcomes. Our primary outcome was the rate of intraoperative difficulty on the modified Nassar scale (MNS). Statistical analysis was performed using SPSS version 25.0 (IBM Corp., Armonk, NY). RESULTS: We included 70 patients who underwent LC for gallstones (CVS not achieved = 24 and CVS achieved = 46). The mean (SD) age was 42.2 (12.3) years, and 73.5% were females. The mean (SD) weight in our study cohort was 74.1 (10.9) kg, and there was no difference between the two groups in terms of the baseline demographic characteristics, disease characteristics, and comorbid conditions (p > 0.05). On univariate analyses, achieving CVS was associated with lower rates of higher-grade operative difficulty on the MNS and lower rates of length of stay of more than one day. CONCLUSION: Achieving CVS is associated with easy LC based on significantly lower Nassar scores. These findings highlight the role of the MNS in the successful identification of the operative difficulty of LC and its correlation with achieving CVS.

RESUMEN

A series of 3-substituted and 3,5-disubstituted rhodanine-based derivatives were synthesized from 3-aminorhodanine and examined for α-amylase inhibitory, DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities in vitro. These derivatives displayed significant α-amylase inhibitory potential with IC50 values of 11.01-56.04 µM in comparison to standard acarbose (IC50 = 9.08 ± 0.07 µM). Especially, compounds 7 (IC50 = 11.01 ± 0.07 µM) and 8 (IC50 = 12.01 ± 0.07 µM) showed highest α-amylase inhibitory activities among the whole series. In addition to α-amylase inhibitory activity, all compounds also demonstrated significant scavenging activities against DPPH and ABTS radicals, with IC50 values ranging from 12.24 to 57.33 and 13.29-59.09 µM, respectively, as compared to the standard ascorbic acid (IC50 = 15.08 ± 0.03 µM for DPPH; IC50 = 16.09 ± 0.17 µM for ABTS). These findings reveal that the nature and position of the substituents on the phenyl ring(s) are crucial for variation in the activities. The structure-activity relationship (SAR) revealed that the compounds bearing an electron-withdrawing group (EWG) at para substitution possessed the highest activity. In kinetic studies, only the km value was changed, with no observed changes in Vmax, indicating a competitive inhibition. Molecular docking studies revealed important interactions between compounds and the α-amylase active pocket. Further advanced research needs to perform on the identified compounds in order to obtain potential antidiabetic agents.

RESUMEN

Human immunodeficiency virus (HIV)/acquired immundeficiency syndrome (AIDS) is a critical global public health problem that significantly affects both life expectancy and the overall quality of life of individuals in all age groups. The landscape of HIV infection has changed significantly in recent years due to the introduction of effective combination antiretroviral therapies (ART). A key component of first-line ART regimens for HIV treatment is abacavir, a nucleoside HIV reverse transcriptase inhibitor. Although abacavir is effective in suppressing viral replication and managing disease, its clinical utility is overshadowed by the potential for life-threatening hypersensitivity reactions in HLA-B*57:01-positive patients. In our country, local data obtained from various centers regarding the prevalence of HLA-B*57:01 in HIV-1-infected patients are available. In this study, it was aimed to determine the prevalence of the HLA-B*57:01 genotype in HIV-infected patients who were followed up and treated in many regions of our country. This retrospective study consists of the data of the patients aged 18 years and over diagnosed with HIV-1 infection between 01.01.2019 and 31.07.2022. Age, gender, place of birth, mode of transmission of the disease, death status, CD4+ T cell count and HIV RNA levels at the first clinical presentation, HLA-B*57:01 positivity, and the method used, clinical stage of the disease, virological response time with the treatment they received were recorded from the patient files. Data were collected from 16 centers and each center used different methods to detect HLA-B*57:01. These methods were sequence-specific oligonucleotide probe hybridization (SSOP), DNA sequence-based typing (SBT), single-specific primer-polymerase chain reaction (SSP-PCR), allele-specific PCR (AS-PCR) and quantitative PCR (Q-PCR). A total of 608 HIV-infected individuals, 523 males (86%) and 85 females (14%), were included in the study. The mean age of the patients was 36.9 ± 11.9 (18-73) years. The prevalence of HLA-B*57:01 allele was found to be 3.6% (22 patients). The number of CD4+ T lymphocytes in HLA-B*57:01 allele-positive patients was > 500/ mm3 in 10 patients (45.5%), while the number of CD4+ T lymphocytes in HLA-B*57:01 negative patients was > 500/mm3 in 216 patients (36.9%) (p> 0.05). Viral load at the time of diagnosis was found to be lower in patients with positive HLA-B*57:01 allele but it was not statistically significant (p> 0.05). Although different treatment algorithms were used in the centers following the patients, it was observed that the duration of virological response was shorter in HLA-B*57:01 positive patients (p= 0.006). Although the presence of the HLA-B*57:01 allele has a negative impact due to its association with hypersensitivity, it is likely to continue to attract interest due to its association with slower progression of HIV infection and reduced risk of developing AIDS. In addition, although the answer to the question of whether it is cost-effective to screen patients for HLA-B*57:01 before starting an abacavir-containing ART regimen for the treatment of HIV infection is being sought, it seems that HIV treatment guidelines will continue to recommend screening to identify patients at risk in this regard.

RESUMEN

AIM: Brucellosis is a zoonotic infection that can affect almost every organ. A mild elevation of aminotransferase levels is usually observed in liver involvement. However, the development of clinical hepatitis is rare. In this study, we aimed to present the hospitalized cases with brucellosis hepatitis in our clinic in a 13-year period. METHODS: A hundred and three patients with significant hepatobiliary involvement, diagnosed by microbiological analysis, were included in the study. For the presence of hepatitis, it was required that the aminotransferases must be ≥ 5 times more than the upper limit and/or the total bilirubin level must be ≥ 2 mg/dl and/or the local hepatic lesion must be demonstrated. RESULTS: Of the cases, 35.9%, 17.5%, and 46.6% had clinical hepatitis, cholestatic hepatitis, and both clinical and cholestatic hepatitis, respectively. The most frequent symptom was fever (85.4%) while the most preferred treatment options were combinations containing aminoglycosides. It was observed that the mean time-interval to decrease to normal values of ALT, AST, and bilirubin values was 15.2 ± 7.8 days while the patients having their treatment regimens. In our study, which focused on liver involvement, it was found that a chronic liver disease did not develop in any of the cases. CONCLUSION: Our study showed that, even in the presence of hepatitis, clinical response and laboratory improvement were high with appropriate treatment. It was observed that the improvement in aminotransferases and total bilirubin values delayed in the cases with blood culture positivity, secondary organ involvement, and alanine aminotransferase/aspartate aminotransferase > 1.

RESUMEN

A lab-scale gravity-driven bioreactor (GDB) was designed and constructed to evaluate the simultaneous treatment of black liquor and domestic wastewater. The GDB was operated with a mixture of black liquor and domestic wastewater at a ratio of 1:1 and maintained at an average organic loading rate of 1235 mg-COD/L-Day. The wastewater was fed to the primary sedimentation tank at a flow rate of approximately 12 mL/min and subsequently passed through serially connected anaerobic and aerobic chambers with the same flow rate. Each wastewater sample was allowed to undergo a hydraulic retention time of approximately 72 h, ensuring effective treatment. The GDB was actively operated for nine samples (W1-W9) at a weekly frequency. The entire process was conducted within the workstation's ambient temperature range of 30-35 °C to sustain microbial activity and treatment efficiency in an open environment. The performance of the GDB was evaluated in terms of various pollution indicators, including COD, BOD5, lignin removal, TDS, TSS, EC, PO43-, SO42-, microbial load (CFU/mL and MPN index), total nitrogen, and color reduction. The results showed that the GDB achieved promising treatment efficiencies: 84.5% for COD, 71.80% for BOD5, 82.8% for TDS, 100% for TSS, 74.71% for E.C., 67.25% for PO43-, 81% for SO42-, and 69.36% for TN. Additionally, about 80% reduction in lignin content and 57% color reduction were observed after the treatment. The GDB substantially reduced microbial load in CFU/mL (77.98%) and MPN (90%). This study marks the first to report on wastewater treatment from two different sources (black liquor and domestic wastewater) using a simple GDB design. Furthermore, it highlights the GDB's potential as a cost-effective, environmentally friendly, and efficient solution for wastewater treatment, with no need for supplementary chemical or physical agents and zero operational costs.

RESUMEN

BACKGROUND: The aim of this study was to determine how the levels of peptide and protein-based biomarkers in cerebrospinal fluid change in bacterial, tuberculous, and aseptic meningitis, and to determine the success of these agents in distinguishing between different types of infectious meningitis. METHODS: The levels of arachidonate-5-lipoxygenase, S100 calcium-binding protein B, defensin-α 1, and glial fibrillary acidic protein in cerebrospinal fluid samples from 20 tuberculosis, 40 bacterial, 25 aseptic meningitis patients, and 55 control groups were measured and compared using an enzyme-linked immunosorbent assay. RESULTS: The mean age of the patients was 37.9 ±â€…14.4 years. The parameter that contributed the most to the differential diagnosis of the infectious meningitis groups was S100 calcium-binding protein B. The S100 calcium-binding protein B levels were significantly higher in the tuberculous meningitis group than in the other groups, and arachidonate-5-lipoxygenase levels were significantly higher in the tuberculous meningitis and bacterial meningitis groups (P < .05). CONCLUSION: This study showed that cerebrospinal fluid arachidonate-5-lipoxygenase, and S100 calcium-binding protein B levels may differ in bacterial, aseptic, and tuberculous meningitis, and the results obtained may be quite effective as important potential biomarkers in the differential diagnosis of different types of meningitis.

RESUMEN

Pedilanthus leaf curl virus (PeLCV) is a monopartite begomovirus (family Geminiviridae) discovered just a few decades ago. Since then, it has become a widely encountered virus, with reports from ca. 25 plant species across Pakistan and India, indicative of its notable evolutionary success. Viruses mutate at such a swift rate that their ecological and evolutionary behaviors are inextricably linked, and all of these behaviors are imprinted on their genomes as genetic diversity. So, all these imprints can be mapped by computational methods. This study was designed to map the sequence variation dynamics, genetic heterogeneity, regional diversity, phylogeny, and recombination events imprinted on the PeLCV genome. Phylogenetic and network analysis grouped the full-length genome sequences of 52 PeLCV isolates into 7 major clades, displaying some regional delineation but lacking host-specific demarcation. The progenitor of PeLCV was found to have originated in Multan, Pakistan, in 1977, from where it spread concurrently to India and various regions of Pakistan. A high proportion of recombination events, distributed unevenly throughout the genome and involving both inter- and intraspecies recombinants, were inferred. The findings of this study highlight that the PeLCV population is expanding under a high degree of genetic diversity (π = 0.073%), a high rate of mean nucleotide substitution (1.54 × 10-3), demographic selection, and a high rate of recombination. This sets PeLCV apart as a distinctive begomovirus among other begomoviruses. These factors could further exacerbate the PeLCV divergence and adaptation to new hosts. The insights of this study that pinpoint the emergence of PeLCV are outlined.

RESUMEN

Malaria is an acute fever sickness caused by the Plasmodium parasite and spread by infected Anopheles female mosquitoes. It causes catastrophic illness if left untreated for an extended period, and delaying exact treatment might result in the development of further complications. The most prevalent method now available for detecting malaria is the microscope. Under a microscope, blood smears are typically examined for malaria diagnosis. Despite its advantages, this method is time-consuming, subjective, and requires highly skilled personnel. Therefore, an automated malaria diagnosis system is imperative for ensuring accurate and efficient treatment. This research develops an innovative approach utilizing an urgent, inception-based capsule network to distinguish parasitized and uninfected cells from microscopic images. This diagnostic model incorporates neural networks based on Inception and Imperative Capsule networks. The inception block extracts rich characteristics from images of malaria cells using a pre-trained model, such as Inception V3, which facilitates efficient representation learning. Subsequently, the dynamic imperative capsule neural network detects malaria parasites in microscopic images by classifying them into parasitized and healthy cells, enabling the detection of malaria parasites. The experiment results demonstrate a significant improvement in malaria parasite recognition. Compared to traditional manual microscopy, the proposed system is more accurate and faster. Finally, this study demonstrates the need to provide robust and efficient diagnostic solutions by leveraging state-of-the-art technologies to combat malaria.
