Chapter 2 Impacts of climate change induced hazards and adaptation processes in Bangladesh: an overview

Living with physical hazards is an everyday issue for the people of Bangladesh because different seasons bring different kinds of uncertainties. Sometimes traditional knowledge and practices (Alam, 2007) help them to adjust to these conditions; in some occasions, these hazards turn into catastrophic disasters causing deaths and bringing unbearable damages in different sectors. In addition to the tangible damages incurred due to hazards, in most of the cases, these hazards injure the internal social organizations at different levels (for example, household, community, and institutional) and affect their assets. Thus, the community resilience is greatly weakened, which makes people susceptible to upcoming hazards. Scientists suggest that climate change-induced threats and uncertainties in the forms of erratic rainfall patterns that result in drought conditions and sometimes floods, abnormal foggy conditions, change in the wind direction and the characteristic patterns of seasons, anomalies in the temperature regimes, and the occurrence of cyclones will bring new dimensions to existing situations. These natural hazards, temperature rises, and sea level rise–induced inundations will contribute to the breakdown of the traditional systems of living; they also bring change in topographical factors (for example, flooding), biophysical factors (changes in the crop yields, runoff, risks of the spread of infectious diseases, changes in the vegetation pattern), and socioeconomic factors (per capital income, health, education, population density) (World Bank, 2001).
Prognathodesgeminus, a new species of butterflyfish (Teleostei, Chaetodontidae) from Palau

Abstract A new species of the butterflyfish genus Prognathodes (Chaetodontidae) is described from two specimens collected at a depth of 116 m off Ngemelis Island, Palau. Prognathodesgeminussp. n. is similar to P.basabei Pyle & Kosaki, 2016 from the Hawaiian archipelago, and P.guezei (Maugé & Bauchot, 1976) from the western Indian Ocean, but differs from these species in the number of soft dorsal-fin rays, size of head, body width, and body depth. There are also subtle differences in life color, and substantial differences in the mtDNA cytochrome oxidase I sequence (d ≈ 0.08). Although genetic comparisons with P.guezei are unavailable, it is expected that the genetic divergence between P.guezei and P.geminus will be even greater than that between P.geminus and P.basabei. It is named for the strikingly similar color pattern it shares with P.basabei.
Periphytic diatoms from an oligotrophic lentic system, Piraquara I reservoir, Paraná state, Brazil

Abstract: Knowledge of biodiversity in oligotrophic aquatic ecosystems is fundamental to plan conservation strategies for protected areas. This study assessed the diatom diversity from an urban reservoir with oligotrophic conditions. The Piraquara I reservoir is located in an Environmental Protection Area and is responsible for the public supply of Curitiba city and the metropolitan region. Samples were collected seasonally between October 2007 and August 2008. Periphytic samples were obtained by removing the biofilm attached to Polygonum hydropiperoides stems and to glass slides. The taxonomic study resulted in the identification of 87 diatom taxa. The most representative genera regarding the species richness were Pinnularia (15 species) and Eunotia (14 species). Five species were registered for the first time in Brazil and seven in the State of Paraná. Taxonomic and ecological comments of the species registered are provided.
Enhanced Chemoprevention of Prostate Cancer by Combining Arctigenin with Green Tea and Quercetin in Prostate-Specific Phosphatase and Tensin Homolog Knockout Mice

The low bioavailability of most phytochemicals limits their anticancer effects in humans. The present study was designed to test whether combining arctigenin (Arc), a lignan mainly from the seed of Arctium lappa, with green tea (GT) and quercetin (Q) enhances the chemopreventive effect on prostate cancer. We performed in vitro proliferation studies on different cell lines. We observed a strong synergistic anti-proliferative effect of GT+Q+Arc in exposing androgen-sensitive human prostate cancer LNCaP cells. The pre-malignant WPE1-NA22 cell line was more sensitive to this combination. No cytotoxicity was observed in normal prostate epithelial PrEC cells. For an in vivo study, 3-week-old, prostate-specific PTEN (phosphatase and tensin homolog) knockout mice were treated with GT+Q, Arc, GT+Q+Arc, or the control daily until 16 weeks of age. In vivo imaging using prostate-specific membrane antigen (PSMA) probes demonstrated that the prostate tumorigenesis was significantly inhibited by 40% (GT+Q), 60% (Arc at 30 mg/kg bw), and 90% (GT+Q+Arc) compared to the control. A pathological examination showed that all control mice developed invasive prostate adenocarcinoma. In contrast, the primary lesion in the GT+Q and Arc alone groups was high-grade prostatic intraepithelial neoplasia (PIN), with low-grade PIN in the GT+Q+Arc group. The combined effect of GT+Q+Arc was associated with an increased inhibition of the androgen receptor, the PI3K/Akt pathway, Ki67 expression, and angiogenesis. This study demonstrates that combining Arc with GT and Q was highly effective in prostate cancer chemoprevention. These results warrant clinical trials to confirm the efficacy of this combination in humans.
Comprehensive Tools of Alkaloid/Volatile Compounds–Metabolomics and DNA Profiles: Bioassay-Role-Guided Differentiation Process of Six Annona sp. Grown in Egypt as Anticancer Therapy

Trees of the Annona species that grow in the tropics and subtropics contain compounds that are highly valuable for pharmacological research and medication development and have anticancer, antioxidant, and migratory properties. Metabolomics was used to functionally characterize natural products and to distinguish differences between varieties. Natural products are therefore bioactive-marked and highly respected in the field of drug innovation. Our study aimed to evaluate the interrelationships among six Annona species. By utilizing six Start Codon Targeted (SCoT) and six Inter Simple Sequence Repeat (ISSR) primers for DNA fingerprinting, we discovered polymorphism percentages of 45.16 and 35.29%, respectively. The comparison of the profiles of 78 distinct volatile oil compounds in six Annona species was accomplished through the utilization of GC-MS-based plant metabolomics. Additionally, the differentiation process of 74 characterized alkaloid compound metabolomics was conducted through a structural analysis using HPLC-ESI-MSn and UPLC-HESI-MS/MS, and antiproliferative activities were assessed on five in vitro cell lines. High-throughput, low-sensitivity LC/MS-based metabolomics has facilitated comprehensive examinations of alterations in secondary metabolites through the utilization of bioassay-guided differentiation processes. This has been accomplished by employing twenty-four extracts derived from six distinct Annona species, which were subjected to in vitro evaluation. The primary objective of this evaluation was to investigate the IC50 profile as well as the antioxidant and migration activities. It should be noted, however, that these investigations were exclusively conducted utilizing the most potent extracts. These extracts were thoroughly examined on both the HepG2 and Caco cell lines to elucidate their potential anticancer effects. In vitro tests on cell cultures showed a significant concentration cytotoxic effect on all cell lines (HepG2, HCT, Caco, Mcf-7, and T47D) treated with six essential oil samples at the exposure time (48 h). Therefore, they showed remarkable antioxidant activity with simultaneous cytotoxic effects. In total, 50% and 80% of the A. muricata extract, the extract with the highest migratory activity, demonstrated a dose-dependent inhibition of migration. It was strong on highly metastatic Caco cells 48 h after treatment and scraping the Caco cell sheet, with the best reduction in the migration of HepG2 cells caused by the 50% A. reticulata extract. Also, the samples showing a significant IC50 value showed a significant effect in stopping metastasis and invasion of various cancer cell lines, making them an interesting topic for further research.

Furthermore, a stronger and statistically significant negative correlation was observed between knowledge and cyberbullying practices after schooling as compared to before education. Between the examined preparatory school students' total knowledge and practice scores for preventive techniques of social media cyberbullying before and after education, a highly statistically significant difference was found at P < 0.001. Conclusion: Preventive Strategies education was effective strategy in improving the knowledge and practices regarding social media cyberbullying among preparatory school students. Recommendation: Creating and implementing more ongoing educational programs to raise preparatory school students' awareness level of cyberbullying prevention techniques
Enhanced coal bed methane recovery finalized to carbon dioxide storage

The recovery of coal bed methane can be enhanced by injecting carbon dioxide (CO2) in the coal seam at supercritical conditions. Through an in situ adsorption/desorption process the displaced methane (CH4) is produced and the adsorbed CO2 is permanently stored. This process is called Enhanced Coal Bed Methane recovery (ECBM) and it is a technique under investigation as a possible approach to the geological storage of CO2 in a carbon dioxide capture and storage (CCS) system. ECBM recovery is not yet a mature technology, in spite of the growing number of pilot and field tests worldwide that have shown its potential and highlighted its difficulties. The problems encountered are largely due to the heterogeneous nature of coal and its complex interaction with gases. These issues, which represent the motivation of this research work, need to be addressed both at laboratory and field test scales. The aim of this thesis is therefore to develop experimental and modeling tools that are able to provide a comprehensive characterization of coal required first to understand the mechanisms acting during the process of injection and storage and secondly to assess its potential for an ECBM operation. In particular, sorption data of CO2, CH4 and N2 on several coals from different coal mines worldwide have been measured at conditions typically encountered in coal seams. CO2 maximum sorption capacity per unit mass of dry coal has been found to range between 5% and 14% weight and to depend on coal rank in a non-monotonic way. Moreover, for a specific coal, competitive sorption isotherms of the binary and ternary mixtures of these gases have been obtained, showing that CO2 adsorbs always more than CH4, and CH4 more than N2. This property is of key importance for ECBM application. In order to investigate the coal volumetric behavior upon exposure to an adsorbing gas, two approaches have been followed. In the first, the utilization of a visualization technique allowed to measure the unconstrained expansion of a coal disc, confirming that indeed coal swells when exposed to a gas that is able to adsorb on its surface and penetrate into its structure, whereas exposure
Epitaxial Growth and Characterization of Nanoscale Magnetic Topological Insulators: Cr-Doped (Bi0.4Sb0.6)2Te3

The exploration initiated by the discovery of the topological insulator (BixSb1−x)2Te3 has extended to unlock the potential of quantum anomalous Hall effects (QAHEs), marking a revolutionary era for topological quantum devices, low-power electronics, and spintronic applications. In this study, we present the epitaxial growth of Cr-doped (Bi0.4Sb0.6)2Te3 (Cr:BST) thin films via molecular beam epitaxy, incorporating various Cr doping concentrations with varying Cr/Sb ratios (0.025, 0.05, 0.075, and 0.1). High-quality crystalline of the Cr:BST thin films deposited on a c-plane sapphire substrate has been rigorously confirmed through reflection high-energy electron diffraction (RHEED), X-ray diffraction (XRD), and high-resolution transmission electron microscopy (HRTEM) analyses. The existence of a Cr dopant has been identified with a reduction in the lattice parameter of BST from 30.53 ± 0.05 to 30.06 ± 0.04 Å confirmed by X-ray diffraction, and the valence state of Cr verified by X-ray photoemission (XPS) at binding energies of ~573.1 and ~583.5 eV. Additionally, the influence of Cr doping on lattice vibration was qualitatively examined by Raman spectroscopy, revealing a blue shift in peaks with increased Cr concentration. Surface characteristics, crucial for the functionality of topological insulators, were explored via Atomic Force Microscopy (AFM), illustrating a sevenfold reduction in surface roughness as the Cr concentration increased from 0 to 0.1. The ferromagnetic properties of Cr:BST were examined by a superconducting quantum interference device (SQUID) with a magnetic field applied in out-of-plane and in-plane directions. The Cr:BST samples exhibited a Curie temperature (Tc) above 50 K, accompanied by increased magnetization and coercivity with increasing Cr doping levels. The introduction of the Cr dopant induces a transition from n-type ((Bi0.4Sb0.6)2Te3) to p-type (Cr:(Bi0.4Sb0.6)2Te3) carriers, demonstrating a remarkable suppression of carrier density up to one order of magnitude, concurrently enhancing carrier mobility up to a factor of 5. This pivotal outcome is poised to significantly influence the development of QAHE studies and spintronic applications.

Pulmonary Hypertension and the Gut Microbiome

The gut microbiome and its associated metabolites are integral to the maintenance of gut integrity and function. There is increasing evidence that its alteration, referred to as dysbiosis, is involved in the development of a systemic conditions such as cardiovascular disease (e.g., systemic hypertension, atherosclerosis). Pulmonary hypertension (PH) is a condition characterised by progressive remodelling and vasoconstriction of the pulmonary circulation, ultimately leading to right ventricular failure and premature mortality if untreated. Initial studies have suggested a possible association between dysbiosis of the microbiome and the development of PH. The aim of this article is to review the current experimental and clinical data with respect to the potential interaction between the gut microbiome and the pathophysiology of pulmonary hypertension. It will also highlight possible new therapeutic targets that may provide future therapies.
ASTRONOMY IN THE NETHERLANDS

We describe the state of astronomical research in the Nether- lands per early 2012. We add some notes on its history of this research and on the strategic choices for the future. Compared to the size of the country (16 million people) the Netherlands is maintaining a high profile in astronomical research over a period of more than one century. The pro- fessional research community consists of about 650 people. This includes research staff, postdocs, PhD students, technical staff working on instru- mentation projects and people involved in the operations of ground-based telescopes and astronomical space missions. We do not take into account staff working for international organizations based in the Netherlands. As- tronomical research in the Netherlands is carried out at four university institutes and two national research institutes that fall under the umbrella of the national funding agency NWO. The Netherlands is the host of two in- ternational organizations: ESTEC, the technology division of the European Space Agency (ESA), and the Joint Institute for VLBI in Europe (JIVE). The Netherlands are one of the founding members of the European South- ern Observatory (ESO) and of ESA. This paper will address a number of significant multilateral collaborations.
Understanding and predicting changes in North Atlantic Sea Surface Temperature

The mechanisms associated with sea surface temperature variability in the North Atlantic are explored using observation-based reconstructions of the historical surface states of the atmosphere and ocean as well as simulations run with the Community Earth System Model, version 1 (CESM1). The relationship between air-sea heat flux and SST between 1948 and 2009 yields evidence of a positive heat flux feedback at work in the subpolar gyre region on quasidecadal timescales. Warming of the high latitude Atlantic precedes an atmospheric response which resembles a negative NAO state. The historical flux data set is used to estimate temporal variations in North Atlantic deep water formation which suggest that NAO variations drove strong decadal changes in thermohaline circulation strength in the last half century. Model simulations corroborate the observation-based inferences that substantial changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC) ensued as a result of NAO-driven water mass perturbations, and that changes in the large-scale ocean circulation played a significant role in modulating North Atlantic SST. Surface forcing perturbation experiments show that the simulated low-frequency AMOC variability is mainly driven by turbulent buoyancy forcing over the Labrador Sea region, and that the decadal ocean variability, in uncoupled experiments, derives from low-frequency variability in the overlying atmospheric state. Surface momentum forcing accounts for most of the interannual variability in AMOC at all latitudes, and also most of the decadal AMOC variability south of the Equator. We show that the latter relates to the trend in wind stress forcing of the Southern Ocean, but that Southern Ocean forcing explains very little of the North Atlantic signal. The sea surface height in the Labrador Sea is identified as a strongly buoyancy-forced observable which supports its use as a monitor of AMOC strength.
Residual Immunity from Smallpox Vaccination and Possible Protection from Mpox, China

Among persons born in China before 1980 and tested for vaccinia virus Tiantan strain (VVT), 28.7% (137/478) had neutralizing antibodies, 71.4% (25/35) had memory B-cell responses, and 65.7% (23/35) had memory T-cell responses to VVT. Because of cross-immunity between the viruses, these findings can help guide mpox vaccination strategies in China.
Low-Dose Aspirin in Combination with Transarterial Chemoembolization in Treatment of Unresectable Hepatocellular Carcinoma

Background: Various strategies under investigation aim to improve the outcome of transarterial chemoembolization (TACE). Aspirin demonstrated chemopreventive, antithrombotic and anti-inflammatory properties. Moreover, it has been reported that aspirin may reverse apoptosis resistance in hepatocellular carcinoma (HCC) cell lines. Objective: To explore the clinical impact of adding aspirin with TACE in management of unresectable HCC patients. Patients and Methods : This prospective randomized trial included 60 cases diagnosed as HCC indicated for TACE; who were simply randomized into two arms with ratio 1:1; to control arm and aspirin arm. Aspirin arm patients received 75 mg of aspirin daily for 3 months; we assessed aspirin toxicity and disease outcome. Results : In this study most of side effects of aspirin were of grade I gastrointestinal side effect. 10% of patients in aspirin arm had complete response versus 6.7 % in control arm and 30% had partial response in aspirin arm versus 23% in control arm, 30% of patients in aspirin arm had disease progression versus 40% in control arm. The median progression free survival and Overall survival were not reached for aspirin arm versus 11 and 22 months for control arm (P=0.035 and P=0.036 respectively). Conclusions : Low dose aspirin use in selected unresectable intermediate stage HCC undergoing TACE is tolerable and could be associated with survival benefit.
