The defining feature of a mass extinction and its associated recovery is the global amount of extinction that occurred[1]. However, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction(the sixth mass extinction), which exhibits variable effects among marine ecosystems and environments, and hence geographic areas [1].

Obj.ctive: Xeroderma pigmentosum (XP) is a rare autosomal recessive dermatosis caused by genetic defects of DNA repair. This study was performed to detect and analyze the genes of 2 Uygur patients with XP and their families and assess the patients' phenotypes, which may enrich the understanding of the genetic skin disorder spectrum in Xinj.ang area. Methods: We collected the clinical data from 2 patients with XP and peripheral blood samples from the patients and their family members. The patients' DNA was sequenced and detected by Sanger sequencing, and gene mutations were screened. Results: The proband in family 1 presented with brown maculae at the exposure site and squamous cell carcinoma secondary to a facial rash. The proband had a homozygous nucleotide variation of XPC c.2251-2A> G (A change from A to G in the penultimate position of the intron before the 2251 position in the coding region), which was a shear mutation. In this family, both parents were heterozygous, and no similar mutation detected in the sister. In family 2, the proband had scattered black brown spots and papules on the trunk and limbs. and his younger sister was also a patient. The proband and his younger sister had homonucleotide variation of XPA c.631C> T, which was nonsense mutation, resulting in the codon for Arg No.211 being changed into termination codon (***211X), thus terminating the peptide chain synthesis prematurely. All the normal individuals in the two families were heterozygotes, and homozygous mutations occurred in all the patients, which was consistent with the autosomal recessive inheritance. Conclusion: XP is rare in Uygur population. This study expanded the mutation spectrum of XP and provided a basis for early diagnosis, treatment, prognostic prediction, and prenatal genetic consultation. © 2022 Hospital for Skin Diseases (Institute of Dermatology), Chinese Academy of Medical Sciences, and Chinese Medical Association, published by Wolters Kluwer, Inc.

The northernmost region of South America has great potential for wind energy production and is a strategic area for the energy transition. We analysed data from ERA5-Land global reanalysis from 1980 to 2020 to determine the wind power potential in this area. Our aim was to identify areas with a high potential for wind energy that could be used to supply energy in case of drought in the region or increases in fuel prices. We compared data from 19 meteorological stations located in Colombia with ERA5-Land reanalysis data to generate reliable information for the feasibility and operation of wind farms. According to our analysis, the Colombian Caribbean and Coastal Plain have monthly average wind speeds at 90 m ranging from 4.85 to 10.34 m/s and 3.79 to 6.62 m/s, respectively. Based on wind power density calculations, these regions have the highest wind power density in our study, with a monthly average of between 250 and 399 W/m2. The Caribbean Region had a 69% increase in wind power density from j.nuary to j.ly compared with the annual average. The wind power density in the plains increased from j.nuary to March, while the Mountain Region had higher anomalies from May to October. The Alta Guaj.ra and Paraguana Peninsula have great potential to generate wind energy due to their privileged geographical location. Although ERA5 offers valuable information about wind availability in time and space, it cannot represent the influence of local effects on wind patterns for the Mountain Region. Data from ERA5-Land global reanalysis (1980-2020) are used to determine the wind power potential in the northernmost region of South America to identify areas with a high potential for wind energy, which could be used to supply energy in case of drought or increases in fuel prices.

The study focuses on the transition from conventional energy sources to sustainable renewable energy (RE) in Palestine, particularly in the West Bank and Gaza Strip. The research aims to understand the relationship between key factors and residents' willingness to invest in the RE sector, with a specific focus on the impact of education. Using the unified theory of acceptance and use of technology, the study analyzes data from 400 residents through a questionnaire and employs ordinary least-squares regression analysis with Eviews 12. The key findings indicate that residents' inclination to invest in RE is significantly influenced by factors such as resource availability, knowledge level and power outages. Moreover, the study suggests that educated residents are more likely to invest in RE when factors such as knowledge, effort expectation, enabling conditions and resource availability are relatively high. The conclusion emphasizes the importance of policymakers' allocating sufficient funds to research and development to promote technological innovation in RE sources, thereby enhancing the population's energy efficiency.

Background Estimated 4%-8% of pregnancies are complicated by asthma. Adequate management in this population is critical to minimize complications. Patients presenting with asthma exacerbation are typically managed with standard bronchodilators and systemic corticosteroids. However, additional agents may be used in patients with refractory asthma exacerbation. Ketamine has been used in refractory bronchospasm, although its efficacy in published literature is heterogeneous. Case Presentation We present a case of a pregnant patient with severe asthma exacerbation refractory to standard and salvage treatment who achieved termination of bronchospasm with ketamine infusion. Conclusion After receiving ketamine infusion for several days, the patient had improved air flow and achieved successful extubation, without experiencing rebound bronchospasm. Although this individual clinical case alone cannot change guidelines or directives to use in refractory asthma exacerbations, it offers a possible treatment option to patients and providers in unusually severe cases with extenuating risk factors. © Wolters Kluwer Health, Inc.
