Authors: Akram Jabbar Abdulhussein  
Published: May 2023

The future of 5G New Radio (NR) development has many significant concerns. To overcome the working frequency band issue, a frequency-reconfigurable patch antenna based on pin diodes is presented and investigated. The antenna's compact dimensions (30 mm x 20 mm x 1.6 mm) are due to its construction on FR-4 substrate material with a relative permittivity of = 4.4. A feed port and two switches allow frequency reconfiguration in the antenna module. C-band service is provided by this antenna module's ability to switch between operating at 3.4 GHz, 4.8 GHz, and 7.5 GHz. Simulation of the proposed antenna is accomplished in the CST microwave studio. The presentation and discussion of the radiation pattern and S parameter demonstrate the feasibility of the proposed antenna. Antenna module's size and performance are both precisely appropriate.

Published: May 2023

Preeclampsia (PE) is a significant contributor to maternal morbidity and mortality that manifests as new-onset hypertension after 20 weeks of pregnancy with signs of uteroplacental or maternal organ dysfunction or proteinuria. This condition is linked to intrauterine growth restriction, preterm birth, placental abruption, fetal distress, and fetal death in utero. The findings of the recent study can be summed up as follows: Hematoxylin and eosin staining of placenta tissues revealed a significant area of calcification in the villous stroma. Additionally, increased collagen fibers around blood vessels and varying degrees of mononuclear cell infiltration are caused by capillary and vein congestion. The Masson's Trichrome stain revealed deposited fibrin between decidual cells and extra-villous cytotrophoblasts, which were surrounded by mature intermediate and terminal villi. Congestion of veins with increased fibrin deposits around veins and arterial vessels with increased fibrocytes When the data was statistically analyzed, it was discovered that PE pregnant women had significantly p<0.05 higher levels of serum TNF- α , than normotensive women ( NT ). Finally, the study found a link between preterm PE and women's pregnancy, as well as histopathologic and immunological parameters in preterm PE and NT women.

Assessment of heavy metal contamination of soils in mechanic workshop at Nekede and Orji, Imo State was carried out using triplicate soil samples at depths of 0 – 15 cm from three sampling points and a control sample - sample point 1 (SP) 20m away from (SP2) and 40m from (SP 3), control point, 1km away from each of the automobile workshops. A total of twelve (12) solil samples were collected using a soil auger. The soil samples were analysed for the following heavy metals (Lead, Copper, Zinc and Nickel) using AA Atomic Absorption Spectrophotometer. Data generated were subjected to statistical analysis such as means and Standard deviation using least significant difference (LSD). Results showed lower concentrations of the heavy metals in soil from control point as compared to soil samples collected from mechanic workshops. Across the sampling point, Zn, Pb, Cu and Ni had concentrations 1.75-89 mg/kg, 1.15-51.15 mg/kg, 0.55-29.35 mg/kg and 0.3-4 mg/kg respectively. Mean concentrations of Zn (49.27 mg/kg), Pb (23.70 mg/kg), Cu (18.25 mg/kg) and Ni (3.58 mg/kg) were higher in the soil samples from auto workshops of Orji compared to Nekede. Across the different sampling points, both Zn (89 mg/kg) and Pb (15.36 mg/kg) were higher in Nekede SP 1 whereas Cu (29.35 mg/kg) and Ni (4 mg/kg) were higher in Orji SP 1 and SP 2 respectively. Assessment of the extent of lead contamination / pollution showed that Zn contamination ranged from very slight Pb varied from very slight, moderate, Cu ranged from low- very low concentration, while Ni varied from very slight’ slight. The study therefore, recommends the control and supervision in the use of land allocated as mechanic workshop to reduce the accumulation of heavy metals.

Published: May 2023

AbstractHalide perovskites have broad bandgap tunability, making them suitable for diverse applications in optoelectronics and photovoltaics. The optical bandgap of halide perovskites varies almost linearly with the halide ionic size, and therefore, it can be controlled through compositional engineering. However, the mechanism underlying this low‐bandgap variation is not yet fully understood. Thus, this study comprehensively investigates the bandgap bowing of cesium–lead mixed‐halide perovskites using compositional engineering and demonstrates that bandgap bowing is extremely small in a variety of compositions including Cl, Br, and I. Subsequently, through density functional theory calculations, it is suggested that the antibonding character of the valence band maximum, tilt distortion of halide ions, and entropy effect leading to equal participation of various halide ions around Pb are collectively responsible for the small bandgap bowing.

The method uses Na2S2O5 as sulfur dioxide source along with 4‐alkyl‐substituted Hantzsch esters as radical precursors for accessing sulfonyl radicals, and allows for the synthesis of 2‐sulfonated 9H‐pyrrolo[1,2‐a]indoles.
Rethinking Antigen Source: Cancer Vaccines Based on Whole Tumor Cell/tissue Lysate or Whole Tumor Cell
Authors: Diao Lu , Liu Mi 
Published: May 2023

AbstractCancer immunotherapies have improved human health, and one among the important technologies for cancer immunotherapy is cancer vaccine. Antigens are the most important components in cancer vaccines. Generally, antigens in cancer vaccines can be divided into two categories: pre‐defined antigens and unidentified antigens. Although, cancer vaccines loaded with predefined antigens are commonly used, cancer vaccine loaded with mixed unidentified antigens, especially whole cancer cells or cancer cell lysates, is a very promising approach, and such vaccine can obviate some limitations in cancer vaccines. Their advantages include, but are not limited to, the inclusion of pan‐spectra (all or most kinds of) antigens, inducing pan‐clones specific T cells, and overcoming the heterogeneity of cancer cells. In this review, the recent advances in cancer vaccines based on whole‐tumor antigens, either based on whole cancer cells or whole cancer cell lysates, are summarized. In terms of whole cancer cell lysates, the focus is on applying whole water‐soluble cell lysates as antigens. Recently, utilizing the whole cancer cell lysates as antigens in cancer vaccines has become feasible. Considering that pre‐determined antigen‐based cancer vaccines (mainly peptide‐based or mRNA‐based) have various limitations, developing cancer vaccines based on whole‐tumor antigens is a promising alternative.

Published: May 2023

AbstractCyclopropene hydrofunctionalization has been a promising strategy for accessing multi‐substituted cyclopropanes; however, cyclopropene hydroalkylation remains underdeveloped. Herein, we report a low‐valent CoH‐catalyzed facial‐selective cyclopropene hydroalkylation to access multi‐substituted cyclopropanes. This reaction exhibits a broad substrate scope of alkyl halides and cyclopropenes and tolerates many functional groups. Moderate‐to‐good facial‐selectivity is obtained without any directing groups. Mechanism studies provide evidence that alkyl radicals are generated from alkyl halides and irreversible CoH insertion is responsible for the facial‐selectivity. Our preliminary exploration demonstrates that asymmetric cyclopropene hydroalkylation can be realized without conspicuous auxiliary groups.
