RESUMEN

Schizophrenia is a major psychotic disorder affecting nearly 23.6 million people globally and greatly impacting the cognitive and social functioning of individuals. Multiple risk factors, including genetic, environmental, and epigenetic factors have been identified. However, the exact mechanism by which some factors aid in the development of schizophrenia is still uncertain. Acute and/or long-standing inflammation has been implicated as both a cause and effect of schizophrenia. Heightened immune responses have been documented in large cohorts of individuals with schizophrenia. While not completely known, multiple hypotheses, such as disruption of the blood-brain barrier, alterations in the kynurenine/tryptophan pathway, and increased microglial activation, have been presented to correlate inflammation with schizophrenic symptoms. Measurement of C-reactive protein (CRP) is a commonly performed and inexpensive test on patients' serum to determine levels of systemic inflammation in the body. Multiple studies have reported an elevated CRP level in different stages of schizophrenia, indicating its potential to be used as a viable biomarker in the diagnosis and monitoring of schizophrenia along with assessing treatment response to conventional and non-conventional treatment regimens. This review aims to evaluate the role of inflammation, in general, and CRP, in particular, in the pathogenesis of schizophrenia and its potential significance in diagnostic, therapeutic, and preventative approaches towards schizophrenia and psychosis.

RESUMEN

Alzheimer's disease (AD), a progressive neurodegenerative disorder, characterized by central cognitive dysfunction, memory loss, and intellectual decline poses a major public health problem affecting millions of people around the globe. Despite several clinically approved drugs and development of anti-Alzheimer's heterocyclic structural leads, the treatment of AD requires safer hybrid therapeutics with characteristic structural and biochemical properties. In this endeavor, we herein report a microwave-assisted synthesis of a library of quinoline thiosemicarbazones endowed with a piperidine moiety, achieved via the condensation of 6/8-methyl-2-(piperidin-1-yl)quinoline-3-carbaldehydes and (un)substituted thiosemicarbazides. The target N-heterocyclic products were isolated in excellent yields. The structures of all the synthesized compounds were fully established using readily available spectroscopic techniques (FTIR, 1H- and 13C-NMR). Anti-Alzheimer potential of the synthesized heterocyclic compounds was evaluated using acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. The in vitro biochemical assay results revealed several compounds as potent inhibitors of both enzymes. Among them, five compounds exhibited IC50 values less than 20 µM. N-(3-chlorophenyl)-2-((8-methyl-2-(piperidin-1-yl)quinolin-3-yl)methylene)hydrazine carbothioamide emerged as the most potent dual inhibitor of AChE and BChE with IC50 values of 9.68 and 11.59 µM, respectively. Various informative structure-activity relationship (SAR) analyses were also concluded indicating the critical role of substitution pattern on the inhibitory efficacy of the tested derivatives. In vitro results were further validated through molecular docking analysis where interactive behavior of the potent inhibitors within the active pocket of enzymes was established. Quinoline thiosemicarbazones were also tested for their cytotoxicity using MTT assay against HepG2 cells. Among the 26 novel compounds, there were five cytotoxical and 18 showed proliferative properties.

RESUMEN

Liver is a vital organ and is routinely exposed to toxins. Carbon tetrachloride is one such noxious agent which cause toxicity in liver when CYP450 enzyme bio-activates it. Many hepatoprotective agents are available in market with severe side effects. Appropriate agent is required to combat such liver problems. Azole compounds have much therapeutic values in many diseases. Based upon this fact, present study is aimed to evaluate the repurposing of Itraconazole in the prevention of hepatic fibrosis via inhibition of cytochrome P450 pathway. For in-vitro evaluation of cyto-protective effects in HepG2 cells (untreated and treated groups), cell viability assays, antioxidant evaluation, enzyme linked immunosorbent assay (ELISA) and immunocytochemistry was used. For in-vivo evaluation, CCl4 induced liver fibrotic rat model was used and post treated evaluation was done by blood biochemistry, hematoxylin and eosin (H&E) staining and gene expression profiling. Results of the current study indicated hepatoprotective role of itraconazole via inhibition of CYP450 pathway inhibition. Therefore, Itraconazole use could be a potential therapeutic approach to prevent liver fibrosis.

RESUMEN

Conventional approaches can repair minor skin injuries; however, severe burn injuries require innovative approaches for efficient and better wound repair. Recent studies indicate that stem cell-based regenerative therapies can restore severe damaged skin both structurally and functionally. The current study aims to evaluate the wound healing potential of skin substitute derived from human neonatal stem cells (hNSCs) using a severe burn injury rat model. Amniotic epithelial cells (AECs) and mesenchymal stem cells (MSCs) were isolated from placenta (a source of neonatal stem cells) by explant culture method. After characterization, AECs and umbilical cord-MSCs were differentiated into keratinocyte and fibroblasts, respectively. Morphological changes, and expression of corresponding keratinocyte and fibroblast specific markers were used to verify differentiation into respective lineage. A skin substitute was developed by mixing hNSCs-derived skin cells (hNSCs-SCs) in plasma for transplantation in a rat model of severe burn injury. Results indicated that placenta-derived AECs and MSCs were efficiently differentiated into skin cells, that is, keratinocytes and fibroblasts, respectively, as indicated by morphological changes, immunostaining, and polymerase chain reaction analysis. Further, transplantation of hNSCs-SCs seeded in plasma significantly improved basic skin architecture, re-epithelization rate, and wound healing concurrent with reduced apoptosis. In conclusion, neonatal stem cell-derived skin substitute efficiently improved severe burn wounds in a rat model of burn injury. Unique properties of placenta-derived stem cells make them superlative candidates for the development of "off-the-shelf" artificial skin substitutes for future use.

RESUMEN

Cellular therapies hold promise to alleviate liver diseases. This study explored the potential of allogenic serum isolated from rat with acute CCl4 injury to differentiate adipose derived stem cells (ADSCs) towards hepatic lineage. Acute liver injury was induced by CCl4 which caused significant increase in serum levels of VEGF, SDF1α and EGF. ADSCs were preconditioned with 3% serum isolated from normal and acute liver injury models. ADSCs showed enhanced expression of hepatic markers (AFP, albumin, CK8 and CK19). These differentiated ADSCs were transplanted intra-hepatically in CCl4-induced liver fibrosis model. After one month of transplantation, fibrosis and liver functions (alkaline phosphatase, ALAT and bilirubin) showed marked improvement in acute injury group. Elevated expression of hepatic (AFP, albumin, CK 18 and HNF4a) and pro survival markers (PCNA and VEGF) and improvement in liver architecture as deduced from results of alpha smooth muscle actin, Sirius red and Masson's trichome staining was observed.

RESUMEN

Hepatic oval cells are likely to be activated during advanced stage of liver fibrosis to reconstruct damaged hepatic tissue. However, their scarcity, difficulties in isolation, and in vitro expansion hampered their transplantation in fibrotic liver. This study was aimed to investigate the repair potential of in vitro differentiated hepatic oval-like cells in CCl4 -induced liver fibrosis. BMSCs and oval cells were isolated and characterized from C57BL/6 GFP+ mice. BMSCs were differentiated into oval cells by preconditioning with HGF, EGF, SCF, and LIF and analyzed for the oval cells-specific genes. Efficiency of oval cells to reduce hepatocyte injury was studied by determining cell viability, release of LDH, and biochemical tests in a co-culture system. Further, in vivo repair potential of differentiated oval cells was determined in CCl4 -induced fibrotic model by gene expression analysis, biochemical tests, mason trichrome, and Sirius red staining. Differentiated oval cells expressed hepatic oval cells-specific markers AFP, ALB, CK8, CK18, CK19. These differentiated cells when co-cultured with injured hepatocytes showed significant hepato-protection as measured by reduction in apoptosis, LDH release, and improvement in liver functions. Transplantation of differentiated oval cells like cells in fibrotic livers exhibited enhanced homing, reduced liver fibrosis, and improved liver functions by augmenting hepatic microenvironment by improved liver functions. This preconditioning strategy to differentiate BMSCs into oval cell leads to improved survival and homing of transplanted cells. In addition, reduction in fibrosis and functional improvement in mice with CCl4 -induced liver fibrosis was achieved.

RESUMEN

BACKGROUND: Emerging drug resistance and hindrance of treatment is provoking scientists to search new, less expensive medicinally active compounds. Dental diseases caused by oral pathogens are very frequent chronic infections around the world. The medical potentials of a lot of Pakistani local herbs and herbal combinations is relatively unknown, hence attempted to explore. A study was designed to investigate potential role of local medicinal herbs for example Miswak, Kalonji & Aloe vera as antimicrobial, antioxidant and anti-proliferative agents against oral pathogens and cancer cell line. METHODS: Medicinal extracts were prepared in solvents of different polarities. Their antimicrobial activity was determined alone and in combination against oral pathogens. Antioxidant activity was evaluated through Catalase and Superoxide dismutase assay and anti-proliferative activity was evaluated through 3-(4, 5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide) assay. RESULTS: Plant extracts alone and in combinations were found significantly effective as antimicrobial agent against standard ATCC strains of C. albicans and S. aureus (P ˂0.001). Especially Miwak extract was found highly significant against fungus. Extracts of Kalonji were found significant in inhibiting growth of HeLa cell lines. Miswak and Kalonji showed significant levels of antioxidant activity. CONCLUSION: Medicinal herbs Miswak and Kalonji have potential to be used for therapeutic purposes. Results suggested that herbal medicinal composition can be prepared using these extracts after applying scientific standardization methods.

RESUMEN

Stomal cells derived from Wharton's jelly of human umbilical cord (WJMSCs) are considered as the potential therapeutic agents for regeneration and are getting famous for stem cell banking. Our study aims to evaluate the effects of gestational diabetes on proliferation capacity and viability of WJMSCs. Mesenchymal stromal cells were isolated from Wharton's jelly of human umbilical cords from normal and gestational diabetic (DWJMSCs) mothers. Growth patterns of both types of cells were analyzed through MTT assay and population doubling time. Cell survival, cell death and glucose utilization were estimated through trypan blue exclusion assay, LDH assay and glucose detection assay respectively. Angiogenic ability was evaluated by immunocytochemistry and ELISA for VEGF A. Anti-cancerous potential was analyzed on HeLa cells. DWJMSCs exhibited low proliferative rate, increased population doubling time, reduced cell viability and increased cell death. Interestingly, DWJMSCs were found to have a reduced glucose utilization and anti-cancerous ability while enhanced angiogenic ability. Gestational diabetes induces adverse effects on growth, angiogenic and anti-cancerous potential of WJMSCs.

RESUMEN

Deep eutectic solvents (DESs) have emerged as new promising solvents in the field of "green chemistry," which possess a broad range of potential applications. However, the ecotoxicological profile of these solvents is still poorly known. In this study, ammonium-based deep eutectic solutions with glycerol (2:2), ethylene glycol (1:2), and diethylene glycol (1:2) as hydrogen bond donors in 1:2 proportion were evaluated for their interaction with various biological systems, including gram-positive and negative bacteria, fungi, fish, and human fibroblast cell lines. The DES synthesis was confirmed by Fourier transform infrared spectroscopy analysis, which analyses the interactions between DES precursors for their synthesis. The antimicrobial activity of tetrabutylammonium bromide: ethylene glycol was the most potent, while tetrabutylammonium bromide: diethylene glycol had a higher LC50 against C. carpio fish. Tetrabutylammonium bromide: glycerol was supposed to be the most suitable DES in terms of cell viability percentage (118%) and 2,2-diphenyl-1-picrylhydrazyl scavenging activity (93%). Finally, tetrabutylammonium bromide in glycerol can be considered an eco-friendly solvent due to its lower toxicity in both in vivo and in vitro environments.

RESUMEN

The leaves of Ficus johannis Boiss (F. johannis), commonly known as Fig tree, Anjir, and Teen, are used by the folk medicinal practitioners in Iran for controlling hyperglycemia in diabetic patients. This study investigated the pharmacological basis for antidiabetic effect of the ethanolic extract of F. johannis leaves using in vitro and in vivo experimental models. Qualitative screening of phytochemicals, estimation of total phenolic and flavonoid contents, and in vitro antioxidant and α-amylase inhibition assays were performed. Moreover, the High-performance liquid chromatography (HPLC) quantification, acute toxicity, glucose tolerance, and in vivo antidiabetic effect along with the evaluation of gene expressions involved in diabetes mellitus were carried out. Significant quantities of phenolic (71.208 ± 2.89 mgg-1 GAE) and flavonoid (26.38 ± 3.53 mgg-1 QE) were present. Inhibitory concentration (IC50) of the plant extract exhibited an excellent in vitro antioxidant (IC50 = 33.81 µg/mL) and α-amylase (IC50 = 12.18 µg/mL) inhibitory potential. The HPLC analysis confirmed the gallic acid (257.79 mgg-1) as main constituent of the extract followed by kaempferol (22.86 mgg-1), myricetin (0.16 mgg-1), and quercetin (3.22 mgg-1). Ethanolic extract displayed glucose tolerance in normo-glycemic rats. Streptozotocin-induced hyperglycemia declined dose dependently in the extract treated rats with improvement in lipid profile and liver and renal function biomarkers. The F. johannis-treated groups showed an increase in mRNA expressions of glucose transporter 4 (GLUT-4), glucokinase, insulin growth like factor 1 and peroxisomal proliferator activating receptor gamma in pancreas. However, the Glucose-6-phosphatase was downregulated. Present study suggests that the ethanolic extract of F. johannis leaves demonstrates a good anti-diabetic profile by improving insulin sensitivity, GLUT-4 translocation, and carbohydrate metabolism while inhibiting lipogenesis.

RESUMEN

Liver failure represents a serious challenge for cell based therapies. Mesenchymal stem cells (MSCs) possess potential for regeneration of fibrotic liver; however, there is a dire need to improve their hepatic differentiation. This study examines a pretreatment strategy to augment the differentiation potential of MSCs towards hepatic lineage. MSCs were isolated from C57BL/6 wild type mice and were characterized by flow cytometry for CD44 (92.4%), CD90 (96.6%), CD105 (94.7%), CD45 (0.8%) and CD34 (1.4%) markers. To improve the differentiation potential of MSCs towards hepatic lineage, cells were pretreated with injured liver tissue in an in-vitro model, which resulted in high expression of albumin, cytokeratin 8, 18, TAT and HNF1α as compared to untreated MSCs. The efficacy of pretreated MSCs was evaluated by preparing in-vivo mouse model with liver fibrosis by intraperitoneal administration of CCl(4). Pretreated MSCs were transplanted in the left lateral lobe of mice with liver fibrosis and showed enhanced localization and differentiation abilities after 1 month. The expression for cytokeratin 8, 18, albumin and Bcl-xl was up-regulated and that of HGF, Bax and Caspase- 3 was down-regulated in animals transplanted with pretreated MSCs. Sirus red staining also confirmed a significant reduction in the fibrotic area in liver tissue transplanted with pretreated MSCs as compared to untreated MSCs and was concomitant with improved serum levels of bilirubin and alkaline phosphatase (ALP). Therefore, it was concluded that pretreatment with injured liver tissue augment homing and hepatic differentiation abilities of MSCs and provides an improved procedure for the treatment of liver fibrosis.

RESUMEN

COVID-19 continues to spread across borders and has proven to be a challenge for the existing healthcare system. The demand for intensivists has dramatically increased in the United States, in the backdrop of an expected lack of intensivists in many States even before the pandemic. One proposal has been to organize multidisciplinary teams functioning under one intensivist, as this approach would make use of the existing healthcare force and lessen the burden on intensivists. Another recommendation is the adaptation of Tele-ICUs, which have demonstrated constructive outcomes in the past. Moreover, ensuring the provision of all types of personal protective equipment, adequate testing and, other provisions such as mental health support, financial incentives for intensivists should be prioritized. More intensivists should be trained for the future, for which better institutional policies are essential.

RESUMEN

BACKGROUND AND AIM: Ischemic Stroke has been recognized as the principal cause of disability and the third leading cause of mortality worldwide. The aim of this study was to determine the frequency and pattern of dyslipidemia in patients presenting with ischemic stroke at a tertiary care hospital in Karachi, Pakistan and to evaluate the effect of demographic and clinical factors on the frequency and pattern of dyslipidemia in ischemic stroke subjects.   Methods: A cross-sectional study carried on a sample size of 235 patients presenting to the out-patient clinic with paralysis, difficulty in speech, and/or loss of consciousness lasting for one hour or more. Blood samples were analyzed for total cholesterol (TC), triglycerides (TG), low-density lipoproteins (LDL), very low-density lipoproteins (VLDL) and high-density lipoproteins (HDL) by the enzymatic colorimetric methodology. These values were recorded on the pre-defined proforma by the investigators. All analysis was performed using SPSS version 23.0.   Results: The average age of the patients was 50.84±11.51 years and 62.1% of them were males. The frequency of dyslipidemia was observed in more than half (n=134/235, 57.02%) of ischemic stroke patients. Regarding the dyslipidemia pattern, TC, VLDL-C and TG levels were deranged in more than 50% of the cases. The most commonly deranged values were of TC and VLDL-C, followed by TG levels. It was observed that patients with a previous history of DM (73.9%, p=0.002) and HTN (81.3%, p=0.001) had significantly higher rates of deranged lipid profiles. Lipid values were found to be more deranged in patients aged 41-50 years (p=0.002) however, no statistically significant differences were observed with respect to BMI (p=0.192) and symptoms duration (p=0.334).   Conclusions: Dyslipidemia is an important risk factor for ischemic stroke, and elevated LDL-C is usually the lipid fraction implicated in the pathologic mechanism of stroke.

RESUMEN

The SARS-CoV-2 outbreak is an unprecedented event in modern history worldwide. To facilitate speedy and smooth recovery during this time period, an added responsibility is placed upon rehabilitation center counselors, staff and management. In this paper we expose the role that psychiatric rehabilitation plays during the COVID-19 crisis. Since COVID-19 pandemic has remarkably raised mental health concerns, one of the high risks and possibly neglected groups includes individuals undergoing mental health rehabilitation, the impact on which can be significant as compared to the rest of the population. In order to ensure that individuals on the road to recovery are not alone and forgotten during the times of coronavirus crisis they should be provided with adequate resources, such as online meetings and group therapy sessions, assessment, treatment and support by telephone and video consultation and getting the medications they need to recover. This article highlights how the coronavirus pandemic, that has hit hard the health care and all categories of patients affected by mental disorders, is likely to be particularly dramatic for mental health rehabilitation centers. Indeed, the COVID-19 crisis has severely tested the health systems worldwide, reducing sometimes the quality and quantity of care offered to psychiatric patients both hospitalized and not in rehabilitation centers. The main goal of this paper is to raise awareness of the importance, often underestimated, of mental health rehabilitation centers, on which one should invest for the both future of psychological and psychiatric rehabilitation and the current crisis as well.

RESUMEN

Over a span of 1 year, with millions infected, COVID-19 has spread to every part of the world and now poses a health threat to each and every one of us. The outbreak has consequently resulted in multiple health problems such as stress, anxiety, depressive symptoms, insomnia, panic, and denial globally. Several factors have contributed to this rising number of psychiatric consults all over the world. The primary objective of this study was to investigate the impact of COVID-19 pandemic on the mental health of Pakistani population during the second wave of the pandemic in this region. We conducted an online web-based cross-sectional survey comprising 500 participants. The questionnaire assessed the demographic information, attitude, and knowledge concerning COVID-19 outbreak in addition to generalized anxiety disorder (GAD) utilizing the GAD-7 scale and depressive symptoms using the Center for Epidemiology Scale for Depression (CES-D) scale. The response rate of the study was 90.9%. The results of the survey indicated a prevalence of 25.4% of GAD, and 18.8% of depressive symptoms. Furthermore, nearly 34.8% of participants feared contracting COVID-19, 62.8% obtained constant critical updates regarding COVID-19, while 17.6% did not understand the knowledge regarding COVID-19. In the multivariate regression models, GAD was significantly associated with gender, age, and checking constantly of critical updates regarding COVID-19. Similarly, participants under 30 years had a higher risk of developing depressive symptoms than those above (> 30 years). Lastly, participants with no formal education were also found to be more prone to developing depression. We identified a potential threat to mental health during the pandemic.

RESUMEN

BACKGROUND: Drug synergy is the combine effect of drug efficacy. Synergistic combinations of active ingredients have proven to be highly effective and more useful in therapeutics. In contrast, the individual effect of drug is usually undesirable and mostly used for selecting drug-resistant mutations. Purpose of this study was to check synergistic effects of both plants (Barbadensis miller and Marsdenia condurango) against liver and cervical cancer. METHODOLOGY: Culturing of HeLa (cervical cancer cell line) and HepG2 (liver cancer cell line) cells, IC50 evaluation, viability assays (trypan blue, crystal violet), p53 ELISA and immunocytochemistry, MUSE analysis (count and viability), antioxidants (GSH, SOD, CAT), at the end RT-PCR was performed. RESULTS: IC50 evaluation was done of each plant individually and with combination for synergistic effects, IC50 with plants combination (synergism) was applied on further viability assays (trypan blue, crystal violet, MUSE analysis via count and viability kit) p53 ELISA and immunocytochemistry for evaluation of cellular apoptosis, antioxidants assays (GSH, SOD, CAT), and RT-PCR with proliferative and apoptotic markers along with internal control. CONCLUSION: According to current study it was observed that synergistic effect of these plants has more anticancer properties with minimum effective dose. It was also observed that extracts possess the ability to induce apoptosis, restrict proliferation and enhanced oxidative stress.

RESUMEN

The coronavirus disease-19 (COVID-19), first appearing in Wuhan, China, and later declared as a pandemic, has caused serious morbidity and mortality worldwide. Severe cases usually present with acute respiratory distress syndrome (ARDS), pneumonia, acute kidney injury (AKI), liver damage, or septic shock. However, with recent advances in severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) research, the virus´s effect on cardiac tissues has become evident. Reportedly, an increased number of COVID-19 patients manifested serious cardiac complications such as heart failure, increased troponin, and N-terminal pro-B-type natriuretic peptide levels (NT-proBNP), cardiomyopathies, and myocarditis. These cardiac complications initially present as chest tightness, chest pain, and heart palpitations. Diagnostic investigations such as telemetry, electrocardiogram (ECG), cardiac biomarkers (troponin, NT-proBNP), and inflammatory markers (D-dimer, fibrinogen, PT, PTT), must be performed according to the patient´s condition. The best available options for treatment are the provision of supportive care, anti-viral therapy, hemodynamic monitoring, IL-6 blockers, statins, thrombolytic, and anti-hypertensive drugs. Cardiovascular disease (CVD) healthcare workers should be well-informed about the evolving research regarding COVID-19 and approach as a multi-disciplinary team to devise effective strategies for challenging situations to reduce cardiac complications.

RESUMEN

The Coronavirus disease-19 (COVID-19), which first appeared in Wuhan, China, and was later declared a pandemic, has caused significant morbidity and mortality worldwide. Numerous efforts have been made worldwide to understand the disease's physical manifestation. However, less emphasis has been placed on the pandemic's mental health challenges for healthcare workers (HCWs) who played a critical role in fighting the disease. Existing literature shows the detrimental psychological impact and increased incidence of depression and anxiety among HCWs. It is expected that the mental health crisis will become a serious issue affecting HCWs, with long-term negative consequences following COVID. Physicians and nurses already represent the highest risk groups of suicide among the general population, and suicide can be regarded as an occupational hazard in the healthcare industry. Increased workload, burnout and fatigue, multifaceted challenges women HCWs, and increased substance abuse are contributing factors to suicide ideation. In this article, we identify the risk factors of suicide among HCWs, discuss mental health challenges exacerbated by the pandemic and its impact on suicide ideation.
