Tropane alkaloids, especially hyoscyamine (HYO) and scopolamine (SCO), are widely used in medicine for their antispasmodic, anticholinergic, and sedative properties. This study was undertaken to investigate the root and shoot tropane alkaloids production from in vitro shoot tip (as explant) culture of Hyoscyamus niger under different plant growth regulators including auxins (IAA, 2, 4-D, IBA, N...

The heart is a muscle with high energy demands. Hence, most patients with mitochondrial disease produced by defects in the oxidative phosphorylation (OXPHOS) system are susceptible to cardiac involvement. The presentation of mitochondrial cardiomyopathy includes hypertrophic, dilated and left ventricular noncompaction, but the molecular mechanisms involved in cardiac impairment are unknown. One...

BeppoSAX detected luminous 0.2–2.0 keV su-persoft X-ray emission from the recurrent nova U Sco ∼19-20 days after the peak of the optical outburst in February 1999. U Sco is the first recurrent nova to be observed during a luminous supersoft X-ray phase. Non-LTE white dwarf atmosphere spectral models (together with a ∼0.5 keV optically thin thermal component) were fitted to the BeppoSAX spectrum...

The tunable magnetism and reversible phase transformation between SrCoO 2.5 (SCO) HSrCoO (HSCO) have attracted vast research interest; however, the physical origin of weakly ferromagnetism hydrogenated is still unclear. Various point defects, especially H related ones, may play important roles in magnetic order SCO HSCO. In this study, we performed first-principles calculations combined with bo...

We address the issue of maximizing number connected devices in a Narrowband Internet-of-Things (NB-IoT) network using nonorthogonal multiple access (NOMA) downlink. first propose an optimal joint subcarrier and power allocation strategy assuming perfect channel state information (CSI) called stratified device (SDA), which maximizes connectivity under data rate, power, bandwidth constraints. The...

BACKGROUND Many medical procedures routinely use body weight as a parameter for calculation. However, these measurements are not always available. In addition, the commonly used visual estimation has had high error rates. Therefore, the aim of this study was to develop a predictive equation for body weight using body circumferences. METHODS A prospective study was performed in healthy volunte...

The motion and variability of the radio components in the low mass X-ray binary system Sco X-1 have been monitored with extensive VLBI imaging at 1.7 and 5.0 GHz over four years, including a 56-hour continuous VLBI observation in 1999 June. We detect one strong and one weak compact radio component, moving in opposite directions from the radio core. Their relative motion and flux densities are c...

OBJECTIVE The most frequent known genetic causes of severe oligospermia (< 5 million sperm/ml) or azoospermia in men are Klinefelter's syndrome (KS), and deletions in the Y chromosome long arm (Yq). We aimed to compare the function of the pituitary-testicular axis in patients with severe oligospermia or azoospermia, idiopathic or associated with Y chromosome deletions or Klinefelter's syndrome ...

We present phase-resolved spectroscopy of the optical counterparts V 801 Ara and V 926 Sco of the low-mass X-ray binaries 1636-536 and 1735-444. To assist in the interpretation of the spectroscopic observations we derive new ephemerides for the photometric variations of both sources. Superior conjunction of the line emission region occurs at photometric phase ∼0.7 in both sources, which indicat...
