Effects of Salicylic Acid and Glycine Betaine on Gas Exchanges, Proline content and Yield of Potato Cultivars under Water Stress Conditions

This investigation was aimed to study the response of potato plants to water deficit and exogenous application of salicylic acid (SA) and glycine betaine (GB). Potato cultivars, Spirit, Born, Arinda and Banba were experienced under two irrigation regimes, 30 and 60 % depletion of available soil water, and two concentrations of both SA (0.5 and 1.0 mM) and GB (1.0 and 2.0 mM) additionally the control (0.0 mM SA and GB). Gas exchanges, proline content (Pro), root volume (RV), root/shoot ratio (R/S), plant dry mass (PDM), number tuber (NT) and yield of potato cultivars were measured. With the exception of R/S, water deficit led to notable decreases in gas exchanges, RV, PDM, NT and yield of potato cultivars and increases in Pro content. Foliar application of SA and GB resulted in significant increases in photosynthesis (Photo), carbon dioxide concentration in the sub-stomatal chamber (Ci), stomatal conductance (Gs), Pro, PDM and yield in some levels of SA and GB; the level of the increases appeared more when potato plants were grown under water deficit conditions. All the overhead effects supported PDM and yield of potato cultivars to increase by exogenous application of SA and GB and directed to the assumption that water deficit converted harmful effects on potato cultivars could be released by exogenous applied SA and GB

Polytrauma Patients and the Significant Role of the Radiologist Diagnosis Through the Imaging Management

This study aimed at recognizing that images have become important not only for diagnosis but also for treatment, and also lies in the analyzing processes of the imaging diagnosis of multiple trauma patients and the significant role of the radiologist diagnosis through the imaging management. The researchers adopted the survey methodology for gathering data upon the recent worldwide studies concerning the polytrauma patients and the significant role of the radiologist diagnosis through the imaging management. The study concluded that the decision to manage the patient surgically or by percutaneous intervention depends upon the clinical severity and secondarily on the findings of whole body MDCT; which identifies blunt polytrauma related injuries which require intervention. Keywords: Polytrauma, Radiologist, Imaging Management and Diagnosis

The Association Between Hypertension and Insomnia Among Saudi Population: A Cross-Sectional Study

Objective To assess the relationship between hypertension and insomnia among the Saudi population. Methods The study will employ a cross-sectional design to investigate the association between hypertension and insomnia among the Saudi population. This design allows for the collection of data at a single point in time, offering insights into the relationship between the variables. Results The study included 581 participants. The most frequent age among them was 18-28 (n= 266, 45.8 Per Cent), followed by 29-39 (n= 129, 22.2 Per Cent). The most frequent gender among study participants was female (n= 320, 55.1 Per Cent), followed by male (n= 261, 44.9 Per Cent). Study participants' most frequent body mass index was normal 18.5-24.9 kg/m2 (n= 231, 39.8 Per Cent) followed by overweight 25-29.9 kg/m2 (n= 200, 34.4 Per Cent). Marital status among study participants, with most of them being single (n=283, 48.7 Per Cent) followed by married (n= 238, 41 Per Cent). The number of hours of sleep during the day among study participants with most of them had 6-8 hours. Participants were asked if they had difficulty sleeping. There most of the participants were nothing (n= 201, 34.6 Per Cent). On the other hand, 154 participants had middle (26.5 Per Cent). They asked if they had difficulty staying asleep. There most of the participants were nothing (n= 227, 39.1 Per Cent). On the other hand, 152 participants had middle (26.2 Per Cent). Participants were asked if they had trouble waking up early. There most of the participants were nothing (n= 189, 32.5 Per Cent). Followed by middle (n=148, 25.5 Per Cent). Conclusion The results of the study showed that most of the study participants were of normal weight according to their body mass index. Most of them are single. Most participants sleep approximately 6-8 hours a day. The largest percentage of participants work in the government or private sector. Most of them had good social contact

Prospects of Nanotechnology in Clinical Immunodiagnostics

Nanostructured materials are promising compounds that offer new opportunities as sensing platforms for the detection of biomolecules. Having micrometer-scale length and nanometer-scale diameters, nanomaterials can be manipulated with current nanofabrication methods, as well as self-assembly techniques, to fabricate nanoscale bio-sensing devices. Nanostructured materials possess extraordinary physical, mechanical, electrical, thermal and multifunctional properties. Such unique properties advocate their use as biomimetic membranes to immobilize and modify biomolecules on the surface of nanoparticles. Alignment, uniform dispersion, selective growth and diameter control are general parameters which play critical roles in the successful integration of nanostructures for the fabrication of bioelectronic sensing devices. In this review, we focus on different types and aspects of nanomaterials, including their synthesis, properties, conjugation with biomolecules and their application in the construction of immunosensing devices. Some key results from each cited article are summarized by relating the concept and mechanism behind each sensor, experimental conditions and the behavior of the sensor under different conditions, etc. The variety of nanomaterial-based bioelectronic devices exhibiting novel functions proves the unique properties of nanomaterials in such sensing devices, which will surely continue to expand in the future. Such nanomaterial based devices are expected to have a major impact in clinical immunodiagnostics, environmental monitoring, security surveillance and for ensuring food safety
