Inter-Parental Conflict's Persistent Effects on Adolescent Psychological Distress, Adjustment Issues, and Suicidal Ideation During the COVID-19 Lockdown

The current study sought to ascertain the impact of inter-parent conflicts on teenage psychological distress, social and academic adjustment and examine the suicide ideation during the COVID-19. The results found to be alarming as 22% of the individuals displayed suicidal tendencies, with 9% having attempted suicide once, 4.6% having tried suicide twice, and 11% stating that they were likely to do so again. Therefore, the media and the government might host awareness programs and counseling initiatives to promote mental health and prevent suicidal behavior. Moreover, parents may be educated on community level, about the effect of inter-parental arguments on the mental health of their children.

There is need of more researches to determine the use of natural compound to treat different disease.

Antioxidant associated chemoprophylaxis effect of natural spice and green vegetable on hepatotoxicity

This is a case control and cohort study, conducted at Department of Biochemistry in FUAST, compressing 24 number of albino Wistar rats. Illicium verum (star anise) natural spice and green vegetable broccoli are used for chemo-preventive herbal treatment in relation with vitamin C antioxidant activity. Hepatotoxicity was induced in liver of model rats by giving interperitoneally single injection of 200 mg/kg bod weight (B.W) of N-nitrosodiethylamine and orally giving 1 mg/kg BW phenobarbital for 14 days during disease prorogation period. The vitamin C analysis from Illicium verum (star anise), green broccoli, orange juice, orange peel and orange pulp was done by iodometric quantitative and qualitative titration method. Rats were given compound according to their bodyweight as 1 mg/kg B.W. After 14 days (Disease Promotion and Propagation Period) and 28 days (Disease cure period) of treatment behavioral activity was monitored by locomotors activity in open field experiment, stimulatory activity in home cage and anxiolytic effects observed in light and dark apparatus and also in T maze. Behavioral activity were significantly increased in Illicium verum and green broccoli treated rats. Hematological study including hemoglobin (Hb), white blood cells (WBC), red blood cells (RBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW) and Platelets was done by abbot laboratory analyzer cell. The value of Hb and RBC was also significantly increased in star anise and broccoli treated rats, showed proper function of RBC in microcirculation. WBC was also in normal range revealed that no disease regards to bone marrow and leukemia's. The biochemical activity of rats including urea, creatinine, total protein, albumin, globulin, A/G ratio, amylase and calcium in blood serum were analyzed while, liver health or performance was also determined by LFT (liver function test).

Isolation of biotic stress resistance genes from cotton (Gossypium arboreum) and their analysis in model plant tobacco (Nicotiana tabacum) for resistance against cotton leaf curl disease complex

Cotton production is widely effected by Cotton Leaf Curl Virus (CLCuV) in world posing serious losses to cotton yield.The CRT genes from CLCuV resistant G. arboreum and CLCuV susceptible G. hirsutum were cloned and sequenced to know the differences of protein composition in both species. Molecular techniques were used to isolate full length putative biotic stress resistance genes from G. arboreum besides the analysis of identified novel genes in model plant tobacco (Nicotiana tabacum) for resistance to cotton leaf curl disease complex. It was found that transgenic plants over expressing Hydroperoxidelyase (HPL) genes exhibited higher enzyme activity than wild type. In addition the genome sequence information was used for the purpose of gene isolation. Even for the enhanced expression of Calreticulin (CRT), AOS and HPL in G. hirsutum, it still showed susceptibility against CLCuV suggesting alternative genes and pathways involved for the expression of resistance.

Targeted therapies for ROS1-rearranged non-small cell lung cancer

ROS1 gene fusions account for approximately 1-2% of all cases of non-small cell lung cancer (NSCLC). Similarly to anaplastic lymphoma kinase (ALK)-positive NSCLC, patients with ROS1+ NSCLC tend to have minimal smoking and be of the female sex. In most cases, adenocarcinoma is the dominant histology. The ROS1 gene has homology to ALK and this structural similarity formed the basis for utilizing ALK inhibitors for ROS1+ NSCLC. On the basis of impressive progression-free survival of 19.2 months from the PROFILE 1001 trial, crizotinib obtained Food and Drug Administration (FDA) approval as first-line therapy for treatment of ROS1+ NSCLC. Since then, there has been a growing appreciation of the incidence of brain metastases in ROS1+ NSCLC and rates of central nervous system progression on crizotinib. Additionally, appreciation of novel resistance mechanisms to crizotinib has led to the development of newer tyrosine kinase inhibitors (TKIs). In this review, we highlight known and emerging TKIs for the management of ROS1+ NSCLC.

Update on multikinase inhibitor therapy for differentiated thyroid cancer

Curative therapies for radioiodine-refractory differentiated thyroid cancer remain lacking. However, oral multikinase inhibitors often allow for disease control and improved progression-free survival. Two agents, lenvatinib and sorafenib, have been approved for radioiodine-refractory differentiated thyroid cancer on the basis of phase III clinical trials showing marked response rates and improved progression-free survival over placebo. Several other multikinase inhibitors, including apatinib, axitinib, cabozantinib, pazopanib, sunitinib and vandetanib, have also been studied in phase II clinical trials, with varying response rates and comparable progression-free survival. Selective kinase inhibitors, including dabrafenib, vemurafenib, selumetinib and gefitinib, offer a more targeted approach and have also been studied in phase II clinical trials. While the emergence of these treatments has changed the landscape of management of advanced thyroid cancer, clinical challenges remain, and there are many areas of ongoing research.

Exploration of cotton leaf curl virus resistance genes and their screening in Gossypium arboreum by targeting resistance gene analogues

Cotton leaf curl virus (CLCuV) disease is one of the major limiting factors in cotton production, particularly in widely cultivated Gossypium hirsutum varieties that are susceptible to attack by this virus. Several approaches have been employed to explore putative resistance genes in another cotton species, G. arboreum. However, the exact mechanisms conferring disease resistance in cotton are still unknown. In the current study, we used various approaches to identify possible resistance genes against CLCuV infection. We report the identification and isolation of a set of genes involved in the resistance response to viral infestation. PCR products containing genomic DNA gave multiple amplifications with a single primer in most reactions, and 38 fragments were cloned from G. arboreum and G. hirsutum. The sequences of cloned fragments belonged to various pathway genes and uncharacterized proteins. However, five amplified fragments (RM1, RM6, RM8, RM12 and RM31) showed similarity with R genes. Maximum homology (94 %) was observed with G. raimondii toll/interleukin receptor-like protein. BLAST search showed the homology of all resistance gene analogues (RGAs) with more than one chromosome, and multiple hits were observed on each chromosome for each RGA. Expression analysis through RT-PCR identified variable expression levels of the different RGAs in all tested genotypes. The expression level of RGAs differed between symptomatic and asymptomatic plants, with the exception of RGA 395, whose expression level was the same in both diseased and healthy plants. Knowledge of the interaction of these genes with various cotton pathogens could be utilized to improve the resistance of susceptible G. hirsutum and other plant species.

Effect of short chain fatty acids on the expression of free fatty acid receptor 2 (Ffar2), Ffar3 and early-stage adipogenesis

Adipose tissue has a major influence on insulin sensitivity. Stimulation of free fatty acid receptor 2 (FFAR2) has been proposed to influence adipocyte differentiation. We hypothesised that exposing preadipocytes to short chain fatty acids would induce earlier expression of nuclear receptors that co-ordinate adipogenesis, triglyceride accumulation and leptin secretion. 3T3-L1 preadipocytes were differentiated in the presence of 1 μM acetate, 0.1-10 μM propionate or vehicle control. In experiment 1, expression of Ffar2 and nuclear receptor mRNA was measured by quantitative PCR over 48 h following onset of differentiation. In experiment 2, extracellular leptin concentration and intracellular triglyceride content were measured at days 0, 2, 4, 6, 8 and 10 following the onset of differentiation. Control cells exhibited similar temporal dynamics of gene expression, triglyceride accumulation and leptin secretion as reported previously. We were unable to detect expression of Ffar3 mRNA at any stage of differentiation. Consistent with a lack of Ffar2 expression in the first 24 h of differentiation, acetate and propionate had no significant effect on nuclear receptor expression. Furthermore, acetate or propionate treatment did not alter leptin concentration or triglyceride content. In conclusion, we observed no significant effect of propionate or acetate on adipogenesis in 3T3-L1 cells using validated quantitative techniques.

The impact of ethnicity and insurance status on stage of cancer at diagnosis and overall survival of breast cancer

154

Background: Major advances in early diagnosis and treatment of breast cancer (BC) have been achieved with significant declines in mortality. However, not all segments of the United States population have experienced equal benefits from this progress. Though ethnic disparities in BC outcome have been attributed to lack of adequate health insurance, the differences in outcome when insurance and socioeconomic status are similar still exist. We elected to examine the effect of insurance status at diagnosis, and whether race is an independent risk of poor outcome in a population from a community-based cancer database.

Methods: A retrospective study on BC among patients aged 18 to 64 years were identified, between 1993 and 2005, using data from the Tumor Registry at Hurley Medical Center in Flint, Michigan. Patient’s characteristics included age, race, stage at diagnosis, and primary payer. Insurance status was classified as uninsured/Medicaid, private insurance, and Medicare disability (Medicare under age 65). The 5-year overall survival (OS) was calculated, in respect to patient ethnicity, and compared between the three insurance groups using Fisher’s exact test.

Results: A total of 779 patients have been identified with diagnosis of BC. 147 patients were excluded due to incomplete data. 632 patients were analyzed. African Americans were 228 (36%), Caucasians 391 (62%), and other ethnicities 13 (2%). Mean age at diagnosis was (49.21) for African Americans versus (51.35) for Caucasians (p = 0.002). African Americans were more likely to present at advanced stage (III, IV) than Caucasians (17% versus 10%, p = 0.017). However, this difference was not statistically significant when adjusting for insurance status. Although both ethnicities had similar OS in respect of their insurance group, patients with Medicaid/uninsured had significantly lower OS compared to patients with Medicare disability (p = 0.006) and private insurance (p < 0.0001) respectively.

Conclusions: Uninsured/Medicaid patients with breast cancer have worse outcome when compared to patients with Medicare or private insurance. Ethnicity is not an independent risk factor of advanced stage at diagnosis and poorer outcome.

Ethnic disparity of treatment initiation in women diagnosed with breast cancer

189

Background: Despite the major advances in early detection and treatment of breast cancer (BC), African American women, continued to have a higher mortality rates than Caucasians. Many studies have failed to identify a key factor to explain racial disparities in breast cancer outcome. These disparities persist even after controlling for insurance and socioeconomic settings. Data about delays in treatment initiation are limited and inconclusive. We intend to compare the time from diagnosis to the initiation of treatment between African American and Caucasian women diagnosed with BC in a single community-based cancer registry.

Methods: Women aged 18 to 64 years with breast cancer were identified, between 1993 and 2009, using data from the Tumor Registry at Hurley Medical Center in Flint, Michigan. Patient’s characteristics obtained include age at diagnosis, race, stage, date of diagnosis, and date of treatment initiation. All patients were previously insured or became insured after diagnosis. Time from diagnosis to the initiation of treatment was calculated in days and compared between African American and Caucasian women using t-test.

Results: A total of 1016 patients have been identified with diagnosis of BC. 23 patients were excluded due to missing data. 993 patients were analyzed. African Americans were 355 (36%), Caucasians 617 (62%), and other ethnicities 21 (2%). Mean age at diagnosis was (48.9) for African Americans versus (51.45) for Caucasians (p = 0.005). African American women were more likely to present with advanced stage (III, IV) than Caucasians (18% versus 12%, p = 0.009). African American women had significant delay in the treatment initiation of BC compared to Caucasians (31.11 versus 21.52 days, p < 0.0001).

Conclusions: African American women were diagnosed with breast cancer at younger age and more advanced disease than Caucasians. African American women experienced significant delay in the initiation of therapy after diagnosis compared to Caucasians. However, the impact of an average delay of 10 days in treatment on overall survival is unknown. The exact explanation of this disparity is yet to be determined.

Blood pressure distribution in a school age population of Quetta, Pakistan

Standardized measurements of blood pressure, height and weight were obtained in 8-11 years old children, attending school in Quetta, Balochistan, Pakistan. The sample consisted of 427 individuals (219 boys and 208 girls). The blood pressure was measured by auscultatory method. To calculate the body mass index (BMI), the weight (kg) of each subject was divided by the square of the subject's height. Association between various variables and blood pressure was judged through correlation coefficient. The net and joint effect of selected variables on blood pressure variability was calculated using simple/multiple regression. The correlation coefficients with that of systolic blood pressure were 0.365, 0.427 and 0.341 whereas these were 0.397, 0.430 and 0.320 for diastolic blood pressure. Height had a regression coefficient of 0.475 mmHg/cm with systolic pressure and 0.419 mmHg/cm with diastolic blood pressure. Weight had a regression coefficient of 0.878 mmHg/kg and 0.717 mmHg/kg with systolic and diastolic pressure respectively whereas BMI had a regression coefficient of 2.35 mmHg/BMI unit with systolic pressure and 1.79 mmHg/BMI unit with diastolic blood pressure.

Genetic studies in some ethnic groups of Pakistan (Southern Punjab): colour blindness, ear lobe attachment and behavioural traits

Frequency distributions of colour blindness, adherent ear lobe, hand clasping, arm folding and leg folding are reported for different ethnic groups (Balochs, Rajputs, Syeds, Pathans, Araeen and Jats) for Pakistan (Southern Punjab). The F-analysis suggests an insignificant difference between these groups, though the LSD value indicates a significant difference of Balochs with the other groups. The association Chi-square values suggest the independence of the three behavioural traits.
