Intellectual developmental disorder with abnormal behavior, microcephaly and short stature (IDDABS), (OMIM# 618342) is an autosomal recessive condition described as developmental delay, poor or absent speech, intellectual disability, short stature, mild to progressive microcephaly, delayed psychomotor development, hyperactivity, seizure, along with mild to swear aggressive behavior. Homozygous frameshift mutation in Pseudouridine Synthase 7, Putative; (PUS7) OMIM# 616,261 NM_019042.3 and splice acceptor variants in Alpha-Aminoadipic Semialdehyde Synthase; (AASS) OMIM# 605,113 NM_005763.3 was funded. Sonidegib Whole exome sequencing (WES) technique was used as tool to identify the molecular diagnostic test. Different bioinformatics analysis done for WES data and we identified two novel mutations one as frameshift mutation c.606_607delGA, p.Ser282CysfsTer9 in the PUS7 gene and splice acceptor variants c.1767-1 G > A in the AASS gene has been reported. The pattern of family segregation maintained the pathogenicity of this variation associated with abnormal behavior, intellectual developmental disorder, microcephaly along with short stature IDDABS. Further, the WES data was validated in the family having other affected individuals and healthy controls (n = 100) was done using Sanger sequencing. Finally, our results further explained the role of WES in the disease diagnosis and elucidated that the mutation in PUS7 and AASS genes may lead an important role for the development of IDDABS in Saudi family.
(Cav.) Less. (Arnica or Capitaneja) is an endemic plant from Mexico restricted to the western part of the country. The aerial parts are used in traditional medicine for the treatment of wounds and burns. The objective of this investigation was to carry out a pharmacognostic study of
and establish markers that allow for the recognition of the characteristics of the plant and validate its traditional use. The study includes anatomical and chemical characteristics of the plant as well as evaluations of its antioxidant capacity and wound healing ability in a murine model.

An anatomical study of
was performed on the middle part of the leaf and stem. A methanolic extract of this species (VcME) was obtained by methanolic maceration of the aerial parts. Subsequently, a partition of the VcME was made to obtain a hexanic fraction (VcH). The phytochemical preliminary screening and characterization by high-performance liquid chromatography/mass spectrometry (HPLC-ESI/MS) of the VcME and VcH were performed. Theproperties related to its traditional use.
favours wound healing according to physical and histological evaluations. In addition, the characteristics of the middle vein, trichomes and catechin glycosides are potentially useful for the recognition of this species.
This is the first pharmacognostic study of this species that covers the plant anatomy, chemical content and biological properties related to its traditional use. V. crocata favours wound healing according to physical and histological evaluations. In addition, the characteristics of the middle vein, trichomes and catechin glycosides are potentially useful for the recognition of this species.
Beta-thalassemias are a group of inherited blood disorders caused by reduced or absent synthesis of beta chain of hemoglobin resulting in variable phenotypes ranging from clinically asymptomatic individuals to severe anemia symptoms. The objective of this study is to screen for the whole beta gene globulin and the LCR region and its clinical relevance in β-Thalassemia patients.

In this study, we collected 140 blood patients' samples with beta-thalassemia from different areas of Saudi Arabia. DNA was then extracted then the molecular scanning for the whole β-globin gene and the Locus control region (β-LCR) for patients' samples, was run using PCR.

Sixty one mutations found in this study, including 22 new mutations not recorded in the database before. These deletions including (*C-1960-1961 ca/-- del in hbb5) and (*c-519C<T homo, *c-390C<T homo in hbb6) were the highest among beta-thalassemia in the study, which indicates a strong sign of injury associated with the disease. Meanwhile, There are other mutations found most common among patients and was linked with the severity of clinical symptoms including (c-1960-1961 ca/-- del in hbb5), (c-519C<T homo, c-390C<T homo, c-160 G<A het in hbb6), (c.315+282 G<A het, c.316-225G<A het, c.315+342 G > A het in hbb9). Interestingly, the highest percentage in gene deletion occurred in exon 03A by ∼33% of the samples, while the highest percentage in gene addition of the gene occurred in exon 03B by ∼25%.

This study was unique to show several new mutations that would help in diagnosis and treatment. These results should be taken further to set up better management strategies to improve outcomes.

These chaperons execute reactivation of thermally and chemically aggregated protein substrates by cooperating with their partner co-chaperons. We optimized the expression and purification conditions of Tid1-L chaperone. Expression of Tid1-L in E. coli resulted in the formation of inclusion bodies which was further purified to soluble active form using 8 M urea and Ni-NTA column. Also, we investigated the events of the reactivation and disaggregation using aggregated G6PDH, luciferase and insulin as substrates. Incubation of aggregated/denatured enzymes with mortalin but not with Tid1 and/or Mge1 resulted in the initiation of the disaggregation reaction albeit very insignificantly. Under the same conditions coincubating the samples with chaperon and its assisted partners Tid1-L and nucleotide exchange factor Mge1 led to (40%) increase in enzyme activity of G6PDH. Similarly, luciferase activity was synergistically enhanced in the presence of mortlain/Tid1-L/Mge1 chaperones machinery. Chaperone-dependent disaggregation of thermally aggregated insulin showed that addition of Hsp70 and Hsp40 chaperones resulted in fast-track of renaissance reaction and inhibition of amyloid. The present study results conclude the quality of cell-control involves interaction of chaperon Hsp70 and its co-chaperones leading to complex formation with chemically/thermally aggregated substrate eventually causing its reactivation and disaggregation.
