  Background and Objective: A major factor is limiting in the cultivation of melons during the off-season is the poor performance of the most cultivars under suboptimal low temperatures. The current study was conducted to investigate effects of incorporating Prohexadione-Calcium (Pro-Ca) into the priming solutions on low temperature germination and emergence performances of melon (Cucumis melo cv. ‘Kırkağaç 637’) seeds. Materials and Methods: Priming was accomplished by imbibing muskmelon seeds for 4 days at 25°C in darkness in solutions of KNO3 or KH2PO4, each at -1.50 MPa, containing 0, 25, 50, 75 or 100 mg L–1 Pro-Ca. After priming treatment, the seeds were washed with distilled water and dried at 20°C temperature on filter paper for 24 h, then subjected to germination and emergence tests at 15 and 20°C. Results: Priming muskmelon seeds in the presence or absence of plant growth regulators in general improved final germination percentage (FGP), mean germination time (MGT), germination index (GI), final emergence percentage (FEP) and mean emergence time (MET), emergence index (EI) compared to non-primed seeds at both temperatures. Conclusion: The results of the study indicated that inclusion of Pro-Ca into the priming solutions can be used as an effective method to improve low temperature germination performance muskmelon seeds.

  The Tidal Link is constructed to dispose off the drainage water from Nawabshah, Sanghar, Mirpurkhas and Badin districts to Shah Samando Creek. It is connected with brackish water lakes belonging to Run of Kuch and Shah Samando Creek of Arbian Sea in District Badin. These lakes were examined in terms of biological life and water quality. The Sonahro and Mehro are saline lakes rich in primary productivity with 114 species of algae, 17 species of aquatic plants and five species of fresh water fish. Among the fishes Cirrhinus mirgala, Channa marulia, Notopterus notopterus, Oreochromis mossambicu's, Rita rita, Wallagoattu were identified and all are commercially important. Water quality revealed , value of pH as 7.7-8.0, conductivity, 2.74-9.97 mS/cm and salinity 1.5-5.9 ppt with a number of nutrients. Pateji and Cholari are brackish water lakes. Majority of algal flora belong to Bacillarophyta, Cyanophyta and Enteromorpha species of Chlorophyta. Beside, 28 species of fish and 8 species of shrimps were identified.

  Garden cress Lepidium sativum (LS) is an annual plant grown in many regions of Saudi Arabia. In the present study, LS collected from three regions of Saudi Arabia. Water suspension of seed powder was prepared from all samples and gavaged at different concentration (2, 4, 8 g/100/mL) to both adult female and male rats for 3 and 6 weeks, respectively. Blood samples from experimental animals were analyzed for liver functions tests and histopathology of the liver was conducted at the end of the study. Biochemical studies showed an increase in serum total protein with all doses. Albumin was increased at the high dose group however, AST, GGT were within normal levels. ALT and ALK were significantly increased after 3 weeks in males receiving 2 and 4 g kg-1, respectively. Liver parenchyma in the form of vascular dilation and congestion of central and portal veins were observed in low doses (2 and 4 mg mL-1) given for 3 weeks, High doses given for 3 weeks showed peri-portal fibrosis and peri-vascular edema. Bile duct proliferation was a prominent feature in those specimens. Congestion and focal cellular changes were less in samples taken after 6 weeks however, some hepatocytes showed signs of apoptosis. Individual variation was observed in response to dose and duration of feeding. Insignificant differences were showed concerning the sex of animals. Further investigation is needed to clarify the cytological and biological effects of feeding on LS using enzyme immunoassay and electron microscopic study of hepatic tissue.

  Seroma is a common problem after mastectomy, occurring in 30-92% of cases. The aim of this study was to detect the histopathology of postmastectomy seromas and the related changes in tumor necrosis factor-α (TNF-α) serum levels. Unilateral mastectomies were performed on 45 female albino rabbits. On day 7, the area of mastectomy was palpated for the presence of swelling and any fluid was aspirated. A biochemical assay of TNF-α serum from all animals (with and without seroma) and that found in the aspirated fluid was performed. Skin flaps and underlying tissues of the mastectomy region were dissected, fixed in 10% formalin, processed and stained for histopathological examination. Seroma developed in 46.6% of the rabbits. The mean volume of seroma fluids was 3.03±2.21 mL. The level of TNF-α in the serum of rabbits that developed seroma was significantly higher than in those that did not. The tissue surrounding the seromas showed persistent granulation tissue containing fibroblasts, inflammatory cells and a large number of newly formed blood vessels surrounded by extravasated blood. This could be attributed to the increased TNF-α serum level, as discovered by the biochemical study. The inflammatory cell infiltrates mainly consisted of eosinophils as well as lymphocytes, macrophages and plasma cells. The postmastectomy seromas showed altered and delayed wound healing. TNF-α levels were elevated in both the seroma fluid and the serum of animals that developed seroma, possibly indicating its role in seroma development.
