Chronic Musculocutaneous Nerve Injury: An Important Differential in Progressive Arm Atrophy
Younas Umer,Khalil Muhammad Tawab,Yasmeen Rehana,Shafiq Omar,Irshad Imran 대한근전도전기진단의학회 2022 대한근전도 전기진단의학회지 Vol.24 No.3
An isolated musculocutaneous nerve (MCN) injury is a rare condition that can be easily missed if it presents late. A 28-year-old man reported painless and progressive wasting of the right arm for 6 months. On examination, there was visible wasting of the right biceps brachii muscle along with its slight weakness, depressed biceps jerk, and an impaired pinprick sensation in the lateral antebrachial cutaneous nerve distribution. He described a history of a road traffic accident 14 months beforehand. Based on the history and clinical examination, the differential diagnosis included an isolated MCN injury, upper trunk plexopathy, lateral cord plexopathy, C5/6 radiculopathy, and monomelic amyotrophy involving the C5/6 myotomes on the right side. The results of nerve conduction studies and electromyography were consistent with chronic proximal MCN neuropathy (right). In cases of arm wasting without pain or numbness, MCN injury should be included in the differential diagnosis, even in the presence of good power of the elbow flexors. The importance of detailed history-taking and clinical correlation cannot be over-emphasized in such cases.

Performance Analysis of TETRA Technology under Heterogeneous Traffic Flow in VANETs
Tariq Umer,Muhammad Khalil Afzal,Farruh Ishmanov 대한전자공학회 2018 IEIE Transactions on Smart Processing & Computing Vol.7 No.1
The goal of vehicular ad hoc networks (VANETs) is to provide safety and comfort to travelers, drivers, and pedestrians during their journeys on the roads. To support vehicular communications under dynamic traffic conditions and diverse operating environments, different communications technologies have been implemented and tested. The availability of Terrestrial Trunked Radio (TETRA) opens a new path for vehicular communications. To explore these opportunities, in this paper, we carry out a performance analysis of TETRA technology on a higher frequency band of 5.4 GHz for vehicular communications. The graph for bit error under the TU-50 and HT-200 standards for the traffic channel (TCH) 7/2 channel is achieved against different targeted data rates. The implementation of TETRA technology supports a high data rate and reliability in vehicular communications for VANETs. The analysis also shows that the VANET role in emergency and disaster situations where limited communications resources are available can be enhanced using TETRA technology, which can provide communications paths for vehicles in VANETs. Moreover, this technology can also provide future support for the usage of a variety of multimedia services in VANETs in the future.

A correlation study between weather and atmosphere with COVID-19 pandemic in Islamabad, Pakistan
Aslam Bilal,Khalil Umer,Azam Umar,Maqsoom Ahsen 대한공간정보학회 2021 Spatial Information Research Vol.29 No.4
The present research aims to investigate the association amid weather and the most recent pandemic of COVID-19 in Islamabad, the capital of Pakistan. The source of COVID-19 surveillance data for the secondary data analysis was the Pakistan’s Ministry of National Health Services Regulations and Coordination. The weather data obtained from the Pakistan Metrological Department (PMD) was exercised in this research. The components of weather include wind speed (m/s), precipitation level (mm), normal, mean, maximum, and minimum temperature (C). For data analysis, a non-parametric correlation test was used due to the reason that normality was not satisfied. Precipitation level (r = - 0.285; p =0 .022), normal temperature (r = 0.293; p = 0.019) as well as the maximum temperature (r = 0.347; p = 0.005) were very much associated with COVID-19 virus. Pollution data (showing the concentration of NO2) of the specific region comprising the study area extracted from the Sentinel-5P satellite was also compared for the two years (2019 and 2020). Since the country will be entering to a new weather season, the conclusions may well assist the strategy and decision-makers in the deterrence of COVID-19.

The rural and cultural life style of indigenous people of Kuz Abakhel is urging them in touch to folk medicines for treatment of various ailments. Seventy-four plant species were documented that were used by the local people for the treatment of different ailments. These plants were commonly used as an ethno medicine against 49 major different disorders, out of which most commonly happened were; Anemia Anesthetics, unconsciousness, Anoxia etc. The principal medicinal plants with maximum used values were Aesculus indica (Wall.ex Comb) Hook.f (0.998), Ajuga bracteosa (0.996). RFC values; the maximum quoted medicinal plant species by the indigenous drivers are A. indica (RFCs = 0.999), A. bracteosa (0.996), Ajuga niponsis (0.994), Allium cepa (0.993) whereas maximum respondents %age was observed for the same plant species examined through consensus index, the (CI% = 90.84%) was for Aesculus indica and A. bracteosa. The medicinal plant species A. indica mentioned 100% for hepatitis. The diseases like. Anemia, Anesthetics and unconsciousness, Anoxia, Anti-dandruff, Antispasmodic, Arthritis, Body coldness and sexual tonic, Eye disease, Gonorrhea, Infertility, Mouth ulcer, Myiasis, Nerve tonic, Pain killer, Refrigerant, Rheumatism, Septicemia, Throat pain, Toothache, had highest FIC value due to depiction by only a single plant taxa/specie (Nt = 1). The current study exposed the significance to compose and offer a list of all the possible plants that are used in folk and ethnic medicinal practices against various ailments in the unexplored area of Kuz Abakhel and to demonstrate the important medicinal plants for future phytochemical and pharmacological research.
