Introduction: Lower extremity vascular injury can result in either temporary or permanent disability.

Methods: This is a clinical audit involving all patients admitted to our institution from January 2008 to June 2018 of those who had undergone revascularization surgery for lower limb trauma.

Results: Fifty-nine patients were in this study with a mean age of 28.1 years. Most of the patients were motorcyclist involved in road traffic accidents with cars (n=30, 50.8%). The popliteal artery was most commonly seen injury (n=41, 69.5%). The mean duration of ischaemia was 14.1 hours. The limb salvage rate was 89.8%.

Conclusion: Lower extremity vascular injury caused by RTA treated in our institution predominantly involved young patients aged between 18-30 years associated with long bone fractures causing contusion and thrombosis of the popliteal artery.

Effects of moderate-intensity continuous training and high-intensity interval training on serum levels of Resistin, Chemerin and liver enzymes in Streptozotocin-Nicotinamide induced Type-2 diabetic rats.

J Diabetes Metab Disord 2019 Dec 10;18(2):379-387. Epub 2019 Oct 10.

1Faculty of Sport Sciences, Department of Sports Physiology and Pathology, Arak University, Arak, 38156-8-8349 Iran.

Background: The aim of this study was to investigate the effects of of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) in serum resistin, chemerin, insulin, liver enzymes and lipid profiles levels.

Methods: 24 Wistar rats with mean weight of 200 ± 50 g were randomly assigned to non-diabetic rats (ND-Cnt), diabetic control (D-Cnt), diabetic training groups. The diabetic training group received 10 weeks of HIIT (D-HIIT) and MICT (D-MICT) following the induction of diabetes. Evaluating resistin, chemerin and insulin hormones levels through ELISA. FBS and liver enzyme levels were measured by biochemical kits.

Results: HIIT and MICT resulted in a significant decrease in resistin, chemerin and fasting blood glucose ( < 0.05) compared to the D-Cnt (P < 0.05). Serum values of FBS, lipid profiles and liver enzyme ( < 0.05) decreased significantly more in the HIIT group compared with the MICT group (P < 0.05). As well as, the resistin level positively and significantly associated with values of ALT and chemerin level positively and significantly associated with values of ALT, ALP and AST in all rat (P < 0.05).

Conclusion: In general, our findings demonstrated that the HIIT leads to better improvements in serum liver enzyme levels, FBS and lipid profiles compared to MICT. HIIT therefore appears to be an important time-efficient treatment for treatment with type 2 diabetes rats.

The Impact of the Land Cover Dynamics on Surface Urban Heat Island Variations in Semi-Arid Cities: A Case Study in Ahmedabad City, India, Using Multi-Sensor/Source Data.

Sensors (Basel) 2019 Aug 26;19(17). Epub 2019 Aug 26.

Department of Engineering, University of Perugia, via Duranti 93, 06125 Perugia, Italy.

This study examines the behavior of land surface temperature (LST) and surface urban heat island (SUHI) from MODIS data over Ahmedabad city, Gujarat state (India), from 2003 to 2018. Summer and winter LST patterns were analyzed, both daytime and nighttime. Ahmedabad, one of the fastest growing metropolitan cities in India, is characterized by a semi-arid climate. The investigation focuses on the SUHI variations due to warming or cooling trends of both urban and rural areas, providing quantitative interpretations by means of multi-sensor/source data. Land cover maps, normalized differential vegetation index, surface albedo, evapotranspiration, urban population, and groundwater level were analyzed across the years to assess their impact on SUHI variations. Moreover, a field campaign was carried out in summer 2018 to measure LST in several rural and urban sites. During summer daytime, the rural zone exhibits a higher average LST than the urban area, resulting in a mean negative SUHI, typical of arid cities, while a slight positive SUHI (mean intensity of 0.4 °C) during winter daytime is present. An evident positive SUHI is found only during summer (1.8 °C) and winter nighttime (3.2 °C). The negative SUHI intensity is due to the low vegetation presence in the rural area, dominated by croplands turning into bare land surfaces during the pre-monsoon summer season. Higher LST values in the rural area than in the urban area are also confirmed by the field campaign, with an average difference of about 5 °C. Therefore, the impact of the rural LST in biasing the SUHI is evident, and a careful biophysical interpretation is needed. For instance, within the urban area, the yearly intensity of the summer daytime SUHI is not correlated with the evapotranspiration, while the correspondent summer daytime LST exhibits a significant negative correlation (-0.73) with evapotranspiration. Furthermore, despite the city growth across the years, the urban area does not generally reveal a temporal increase of the magnitude of the heat island but an enlargement of its spatial footprint.

Clavicle fracture and subclavian vessels disruption with massive haemothorax mimic intrathoracic injury.

Malays J Med Sci 2011 Apr;18(2):74-7

Department of Orthopaedic, School of Medical Sciences, Universiti Sains Malaysia Health Campus, 16150 Kubang Kerian, Kelantan, Malaysia.

We report a case of open fracture of the clavicle with subclavian artery and vein laceration and perforation of the parietal pleural below the first rib that caused massive haemothorax. Emergency thoracotomy and exploration followed by repair of both vessels were able to salvage the patient and the extremity.

Isolation and lipoxygenase-inhibition studies of phenolic constituents from Ehretia obtusifolia.

Chem Biodivers 2005 Jan;2(1):104-11

H.E.J. Research Institute of Chemistry, International Center for Chemical Sciences, University of Karachi, Karachi-75270, Pakistan.

The phenolic compounds methyl 2-O-feruloyl-1a-O-vanillactate (1), caffeic anhydride (2), and trans 4-hydroxycyclohexyl-2-O-p-coumaroyl beta-D-glucopyranoside (3) have been isolated from the AcOEt-soluble fraction of Ehretia obtusifolia, along with methyl rosmarinate (4) and rosmarinic acid (5), which are reported for the first time from this species. Their structures were determined by means of 1D- and 2D-NMR techniques. Compounds 1-5 inhibited lipoxygenase in a concentration-dependent manner, with Ki values ranging from 0.85-57.6 microM. Compounds 1, 2, 4, and 5 showed noncompetitive inhibition, whereas 3 was found to be an uncompetitive inhibitor of lipoxygenase.
