Specific language impairment (SLI) is a developmental disorder with substantial genetic contributions. A genome-wide linkage analysis and homozygosity mapping were performed in five consanguineous families from Pakistan. The highest LOD scores of 2.

Any defect in accurate speech production ability results in the development of speech sound disorder (SSD), a condition that can significantly impair an individual's academic performance, social interactions, and relationships with peers and adults. This study investigated the genetic basis of SSD in three Pakistani families.

Several reactivity parameters and charge distribution were calculated and the reactivity profile was estimated.

Evidence for the value of ROHs to speech or language-related traits is restricted due to the absence of population-matched behaviourally defined controls and limited family-based studies.
Aim: This study aims to identify common ROHs in the Pakistani population, focussing on the total length and frequency of ROHs of variable sizes, shared ROHs, and their genomic distribution.
Emerging evidence suggests that impaired speech may be related to reduced working memory (WM). The current study aimed to validate and compare the influence of articulation, short-term memory (STM), WM, and receptive vocabulary abilities of Pakistani children with speech sound disorder (SSD; N = 50) versus typically developing (TD; N = 30) children aged 7-13 years. Assessments included the Test for Assessment of Articulation and Phonology in Urdu (TAAPU), Peabody Picture Vocabulary Test-4, translated to Urdu (U-PPVT-4), and Digit Memory Test (DMT) used to determine speech articulation, receptive vocabulary, and memory abilities respectively.

On the basis of non-verbal receptive vocabulary and percentage correct consonants (PCC) scores, children from public schools in Punjab, Pakistan with speech and language issues were separated into three groups; Speech sound disordered (SSD, N = 15), Language Impaired (LI) comorbid with SSD (N = 42) and typically developed (TD, N = 15). Urdu version of Peabody picture vocabulary test, fourth edition (U-PPVT-4), Digit memory test (DMT), and Test for assessment of articulation and phonology in Urdu (TAAPU) were used to assess non-verbal receptive vocabulary, Short-term memory (STM), Working memory (WM), and SSD.

In the present study, a new Ca(II) complex of meloxicam was synthesized and characterized by elemental analysis, FT-IR, UV-Vis, C NMR, SEM-EDX, powder XRD and thermal analysis (TGA). The Ca(II) complex was investigated for its in vitro, in vivo biological activities and in silico docking analysis against COX-1 and COX-2.

An imbalance between reactive oxygen species (ROS) and their elimination by antioxidants damages the cell and infect whole organism. The biological defence system against oxidative stress injury is Kelch-like ECH associated protein 1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response elements (ARE) pathways. Antioxidants activate the Nrf2-ARE-Keap1 pathway and suppress the oxidative stress.

As much as the researchers are inundated for the quest of effective treatments from available drugs, the discovery and trials of new experimental drugs are also at a threshold for clinical trials. There has been much concern regarding the new and targeted drugs considering the comprehensive ambiguity regarding the mechanism and pathway of the drug action with respect to the new and unpredictable structural and nonstructural proteins (NSPs) of SARS CoV-2.

This is particularly true for individuals with specific language impairment (SLI), which is defined as an impairment in normal language development in the absence of any other developmental disability. Although SLI displays high heritability, family-based linkage studies have been hampered by an unclear mode of Mendelian segregation, variable disease penetrance, and heterogeneity of diagnostic criteria.

What is the mechanism of wheat-induced pulmonary inflammation and how does a hydrazide derivative modulate it? What is the main finding and its importance? A hydrazide derivative significantly reduced wheat-induced pulmonary inflammation in a rat model mainly by down-regulating inflammatory cell infiltration, pathological lesions in the lungs and the level of pro-inflammatory cytokines, COX-1, COX-2 and T-cell proliferation.
Abstract: We investigated the ameliorative anti-inflammatory effect of a previously synthesized hydrazide derivative (N'-(4-methoxybenzylidene)-6-(4-chlorophenyl)-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carbohydrazide; MD) as an immunomodulator in a newly developed allergen-induced pulmonary inflammation (AIPI) rat model. Wheat and thresher dust were used as allergens to induce pulmonary inflammation while MD was used to reverse the inflammatory response.
Emerging evidence indicates that many microRNAs (miRNAs) are indispensable regulators of osteoblast differentiation and bone formation. However, the role of miRNAs in mechanotransduction of osteoblasts remains to be elucidated. This study aimed to identify a mechanosensitive miRNA that regulates Activin A receptor type I (ACVR1)-induced osteogenic differentiation.

In the past it was considered as disease of older middle aged women, but the incidence of BC in young females is growing in recent years concordant with studies in Pakistan. In this paper, we reviewed the mutant functions of tumor suppressor genes (BRCA1, BRCA2, p53, ATM and PTEN), epigenetic transformation and involvement of estrogen receptors in development of breast cancer.

Recently, variants in GNPTAB, GNPTG, and the functionally related NAGPA gene have been associated with non-syndromic persistent stuttering. In a worldwide sample of 1013 unrelated individuals with non-syndromic persistent stuttering we found 164 individuals who carried a rare non-synonymous coding variant in one of these three genes.

In this study, whole-exome sequencing was performed with genomic DNA from affected individuals from three large consanguineous families in which markers linked to DFNB86 segregate with profound deafness.
