The present paper deals with a new antiarch- Heteroyunnanolepis qujingensis gen. et sp. nov., collected from the Lower Devonian of Cuifengshan, Qujing, Yunnan in 1990. Only external or internal molds are preserved and available for study,the new genus is attributed to Yunnanolepidae mainly in the light of general similarity to the previously described forms of the family, in particular, axial joint without brachial process, pattern of skull-roof.

The paper discusses the distribution of Quaternary sediments, occurrence of saline minerals and phases of neotectonic movements and their manifestations in the Qaidam basin. The formation of four successive lacustrine terraces in Tertiary anticlinal zones in the western part of the basin was related to the neotectonic movements that took place 100 Ka ago, and the distribution of such terraces discloses, in a way. the evolutionary history of the Quaternary salt lakes. According to the distribution of the terraces coupled with the distribution of Quaternary sediments and features of salt deposition, four periods of Quaternary salt lake evolution in the basin may be distinguished, which correspond to four stages of salt deposition respectively.

Qarhan salt lake which covers an area of 5800 square kilometres is a large playa in Qaidam basin, Qinghai Province. The salt-bearing layers are usually 40 m thick, the maximum thickness being 73 *** sedimentation of the lake has the following basle characteristics: (1) The salt-containing layers are principally composed of interbedded halite and clastic sediments, and they are either lacking in sulfate deposits or deficient in carbonate sediments. (ii) The sedimentary differentiation is not sufficient, and all of the halite layers almost contain mud, sand, carbonates and gypsum in varying degrees; there exist mixtures of gypsum and halite in the intercalations of clastic sediments. (iii) The salt-carrying beds are associated with aeolian deposits. The authors found for the first time that Malan loess exists in the salt-bearing layers of Qarhan salt *** of evolution of palaeoclimate: A lot of evaporite deposits had appeared in Qarhan salt lake by the end of Late Pleistocene, 24,000—25,000 ye

Introduction: Vaccination of children has experienced delays due to paucity of information regarding safety, effectiveness, immunogenicity, and reactogenicity. Age wise approval prioritized 12 - 17 years and later 5 - 11 years. Those below 5 years possess na?ve immunity and not considered. In lake Region Economic Bloc children aged 12 - 17 variably received 1, 2, and 3 doses of vaccine. This analysis looks into effectiveness of the doses administered. Method: Data providers from 84 LREB facilities submitted patients’ vaccination data to Power BI supported dashboard between June 24, 2021 and July 30, 2022. Data of 12 - 17 years old was mined, analyzed and visualized. sample sizes considered for analysis were 0 dose, n = 8132;1 dose, n = 271;2 doses, n = 402, and 3 doses, n = 90. Data used in the analysis was facility operational and not from experimental design. Relative risk analysis of children who received 0, 1, 2, and 3 doses was done using Odds Ratio run on R software. Results: The relative risk of infection to a child with one dose against unvaccinated counterpart is 0.92 (95% CI, 0.61 - 1.43). Likewise the relative risk of infection to a child aged 12 - 17 years with 2 doses against another who received no dose is 0.87 (95% CI, 0.63 - 1.24). A child with 3 doses is 46% (95% CI, 27% - 84%) less likely to get infected compared to another not vaccinated. Also, the relative risk between having 2 doses and 1 dose for a child aged 12 - 17 years is 0.95 (95% CI, 0.55 - 1.6). For the same age group the relative risk of having 3 doses of vaccines against 1 dose is 51% (95% CI, 26% - 100%). In addition, a child who receives 3 doses of vaccine is 53% (95% CI, 28% - 100%) less likely to experience breakthrough infection compared to another with 2 doses. Whereas 1st dose offers (5%) marginal protection advantage over the 2nd dose, the 3r dose offers 49% and 47% more protection over 1st and 2nd doses, respectively, because of incr

The onset of hepatic decompensation in cirrhosis heralds an accelerated downhill course with poor outcome. The sole predictor of this decompensationin cirrhosis is increased hepatic vein to portal vein gradient hepatic venous pressure gradient(HVPG). Surrogate markers of liver function or hepatic reserve appear to be less relevant. The hepatic sinusoids become less elastic and more rigid as liver fibrosis and cirrhosis progress. We propose that the HagenPoiseuille's law,which applies to rigid,but not elastic vessels,determines the pressure-flow characteristics in the sinusoids. In the rigid cirrhotic liver,HVPG rises dramatically with any change in net surface area or radius,r4 of the vasculature that follows surgical resection. This review relates liver stiffness to the risk of decompensation in patients with cirrhosis. The liver has a unique dual blood supply comprising a low pressure portal vein and high pressure hepatic artery. We compare the complexity of autoregulation in the normal elastic liver with that in the rigid cirrhotic liver. Therapeutic modalities to reduce portal pressure may reduce the risk of hepatic decompensation and improve outcomes in cirrhosis.

This paper, based on field data and experimental results, gives an analysis and summary of the types and salt-forming characteristics’ of salt lakes in Xinjiang and the distribution and chemical compositions of their brines and groups of salt minerals. The evolution and substance origins of the salt lakes and their salt-forming regularities as seen from analyses of their .paleogeographic environment and geological tectonics are also reported. This paper will serve as a reference for further investigation of the Xinjiang salt lakes, and as a guide for fuller utilization of their resources.
