Assessment and Exposure Analysis of Trace Metals in Different Age Groups of the Male Population in Southern Punjab, Pakistan.

In developing countries, like Pakistan, the pursuit of urbanization and economic development disrupts the delicate ecosystem, resulting in additional biogeochemical emissions of heavy metals into the human habitat and posing significant health risks. The levels of these trace elements in humans remain unknown in areas at higher risk of pollution in Pakistan. In this investigation, selected trace metals including Copper (Cu), Chromium (Cr), Lead (Pb) Cadmium (Cd), Cobalt (Co), Nickel (Ni), and Arsenic (As) were examined in human hair, urine, and nail samples of different age groups from three major cities (Muzaffargarh, Multan, and Vehari) in Punjab province, Pakistan. The results revealed that the mean concentrations (ppm) of Cr (1.1) and Cu (9.1) in hair was highest in Muzaffargarh. In urine samples, the mean concentrations (µg/L) of Co (93), As (79), Cu (69), Cr (56), Ni (49), Cd (45), and Pb (35) were highest in the Multan region, while As (34) and Cr (26) were highest in Vehari. The mean concentrations (ppm) of Ni (9.2), Cr (5.6), and Pb (2.8), in nail samples were highest in Vehari; however, Multan had the highest Cu (28) concentration (ppm). In urine samples, the concentrations of all the studied metals were within permissible limits except for As (34 µg/L) and Cr (26 µg/L) in Vehari. However, in nail samples, the concentrations of Ni in Multan (8.1 ppm), Muzaffargarh (9 ppm), Vehari (9.2 ppm), and Cd (3.69 ppm) in Muzaffargarh exceeded permissible limits. Overall, the concentrations of metals in urine, nail, and hair samples were higher in adults (39-45 age group). Cr, Cu, and Ni revealed significantly higher concentrations of metals in hair and water in Multan, whereas As in water was significantly (p < 0.001) correlated with urinary As in Multan, indicating that the exposure source was region-specific.

Trypsin Inhibitor Isolated From Glycine max (Soya Bean) Extraction, Purification, and Characterization.

The current study aims to isolate, purify, and characterize the trypsin inhibitor protein from seeds of soya beans, scientifically known as Glycine max. Its seeds were ground, and the powder was soaked several times using n-hexane. It was added to phosphate buffer saline (PBS) followed by filtration and centrifugation of the PBS dissolved extract. The supernatant was subjected to ammonium sulfate precipitation and about six fractions, 30% to 80% were prepared. The centrifuged pellets obtained from each fraction were dialyzed and run on SDS-PAGE. The trypsin inhibitor protein was precipitated and characterized in 30% pellet and molecular weight was 21.5 kDa compared to protein ladder (ThermoFisher 10-170 kDa). GC-MS analysis revealed the steroid derivatives such as stigmasterol, campesterol, beta-sitosterol, and gamma-tocopherol. Glycine max trypsin inhibitor could be used as a plant-derived drug to overcome the over-activation of trypsin without its real substrate (proteins) becoming activated and start auto digestion leading to pancreatitis.

Phytochemical investigation and pharmacological evaluation of methanolic flower extract of Saussurea heteromalla.

Saussurea heteromalla is the one of specie of Saussurea plant belonging to family Asteraceae. The Saussurea heteromalla found extensively in Pakistan. The literature review highlights numerous biological aspects of Saussurea heteromalla. This research therefore aims to assess its potential anti-inflammatory, antioxidant, anti-cancer. Carrageenan induced rat paw edema model was used for the evaluation of anti-inflammatory activity. DPPH method was used to evaluate anti-oxidant activity. The MTT (3- [4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromide) test was used to assess the viability of the cells for the assessment of the cytotoxic effect of the extract. Methanolic Saussurea heteromalla flowers extract analysis carried by GC-MS, result 19 different peaks. The methanolic extract of Saussurea heteromalla at 400mg/kg dose have equal anti-inflammatory action when compare with standard that is diclofenac sodium. Anti-oxidant activity of methanolic extract is also very good. IC50 value of methanol extract was 25µg/ml. 18.72% cell survive out of 100 when methanolic flower extract of Saussurea heteromalla was given at the dose of 400mg, which shows the cytotoxic effect. This activity shows that plant Saussurea heteromalla methanolic flowers extract have anti-inflammatory, anti-oxidant, cytotoxic effect. The isolation and characterization-based investigations proclaiming the biologically leading active molecule are worthy for further study in this regard.

Fibrodysplasia Ossificans Progressiva.

Fibrodysplasia Ossificans Progressiva (FOP) is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of connective tissue and congenital malformation of big toes. We report a 3-year male toddler with clinical and radiological features of FOP. He was born with bilateral hallux valgus and at the age of 3 years presented with hard swellings over back, scapular region and forehead that were initially inflammatory and then became bony hard. There is also tilting of neck towards the left due to calcification in neck region. The radiographs showed heterotopic ossification in thoracic region, neck, spine and region of hip joint.
