The effect of depositional facies and diagenesis on the reservoir potential of the Sakesar Limestone has been assessed through core plug porosity and permeability data， scanning electron microscope (SEM)， and petrographic study in three stratigraphic sections (Karuli， Badshah Pur， and Sardhai) of Central Salt Range. Field observations revealed three lithofacies: thin-bedded limestone with shale intercalation， thick-bedded nodular limestone， and highly fractured limestone. Based on a petrographic study， six microfacies have been identified: Bioclastic Mudstone Facies (SKF-1)， Lockhartia-Nummulitic Wackestone Facies (SKF-2)， Assilina-Alveolina Packstone Facies (SKF-3)， Lockhartia-Nummulitic Packstone Facies (SKF-4)， Alveolina Grainstone Facies (SKF-5)， and Nummulitic Grainstone Facies (SKF-6). The Sakesar Limestone shows various diagenetic changes such as compaction， dissolution， dolomitization， cementation， and fracturing， resulting in different types of pores. Two reservoir zones are identified in the Sakesar Limestone: a mud-dominated reservoir in an outer ramp setting with interparticle and micropores and a bioclastic grain-dominated facies in an inner ramp setting with intraskeletal and fracture porosity. The porosity and permeability of grain-dominated facies (8-30% and 0.8-8 mD) are higher than mud-dominated facies (4-15% and 0.5-4 mD) due to intraskeletal/intraparticle pores and dolomitization.

在Kohat高原,Bahadur Khel盐是最集中的地质区域之一。除了古生物残余物外,还存在着很容易看到的各种各样的地质结构。因此,它被称为地质和化石科学的展览大厅。它也可以看做一份含有丰富岩盐的地质画卷。由于缺乏植被,每一层地层都是有现象出现的。因此,Bahadur Khel盐具有国际科研和教学价值,高度值得保护和保存。取样制备薄片后主要采用显微观察、x射线衍射（XRD）、x射线荧光光谱（XRF）、拉曼光谱（Raman）和显微测温等方法对流体包裹体进行了研究。通过岩相学观察鉴定了流体包裹体的矿物类型,得出大多数包裹体为次生包裹体的结果。对矿物晶体进行了x射线衍射（XRD）分析。评价了盐岩中矿物学、化学成分和微量矿物。而x射线荧光光谱法是一种快速、常规的技术,广泛应用于各种研究领域（包括地质、环境、生物和工业研究）中材料的详细元素组成的测定。利用拉曼光谱对流体包裹体成分进行了分析。显微测温法用于原生包裹体,包括绘制和拍照记录流体包裹体的大小、形状和分布,以及测试前后包裹体中气泡的变化。岩相学研究表明,盐岩主要矿物为石盐（Nacl）。矿物丰富且保存完好。其沉淀温度在5.8～19℃之间,其流体由包含H、O、Na、Cl等成分的大气水构成.其他次要矿物有石膏、硬石膏和次生白云石。X射线荧光光谱（XRF）和X射线衍射（XRD）数据显示了盐岩的化学成分。根据XRF数据,盐岩中最丰富的成分是Na、Cl、O、Ca、Mg、Si、Al、Fe、Br、Sr、K、Zn、P、Ni、Pt和S。XRD表明,盐岩并不纯净。原生和次生晶体中石盐的平均含量分别为94.2%和92.8%。方解石、铁白云石、方解石、硬石膏等微量成分（XRD数据）和镁、钙、氧、钾、硅、铝等（XRF数据）表明,岩石暴露于大气中并与大气水接触。与次生晶体相比,大多数原生晶体表现出较高的密度,显示出较高的饱和度和流体的高浓度。在所有实验分析的基础上,认为Bahadur Khel岩盐包裹体大部分为次生包裹体,是在构造成岩作用后沉积隆升时期形成的。本研究处理和选择的流体包裹体可用于获得古温度的定量记录。本文从Bahadur Khel地区得出的均一温度数据是合理的可接受的,并可解释为古表层盐水的温度。岩盐中的流体包裹体有可能提供一些最好的古气候记录。

Cells are surrounded by a double-layered phospholipid cell membrane responsible for the isolation of intracellular contents, active regulation of uptake from the extracellular environment, and intercellular connection and communication. These cell membranes must be intact and functionally active for cell survival and biological functioning. Compromised damage repair mechanisms usually result in impaired cellular homeostasis, leading to early or late problems. Chronic myopathies, certain myocardial diseases, aging, and acute or chronic neurodegenerative diseases (like Parkinson and Alzheimer) are directly related to cell membrane damage. This study examined the effect of a cholesterol-loaded nanoparticle (methyl-beta cyclodextrin) or the silk protein sericin on cell membrane and DNA integrity and cell viability in an in vitro cell damage model (frozen-thawed rabbit sperm cells). The cells were stored in liquid nitrogen (-196°C), thawed in small batches, and treated with cholesterol-loaded cyclodextrin or sericin before incubation at 35°C for 4 hours. Cell membrane integrity, DNA damage, and viability rates were assessed immediately after thawing and after the incubation period. The administration of sericin and cholesterol in a cell damage model increased cell survival and reduced DNA damage over a 4-hour post-thaw incubation period, suggesting their potential use as a “first aid” intervention at the cellular level.

背景:皮肤由表皮、真皮、皮下组织及其附属器组成。表皮中存在黑素细胞,其负责皮肤颜色并在外观中起主要作用。它在很大程度上决定了我们的外貌,并在我们的社交中产生巨大影响。皮肤问题占家庭诊疗总次数的15-20%,这不仅会导致身体不适,也会给个人和社会带来不便,最终对心理健康产生重大影响。据报道,身体暴露部位(如面部)的器质或感知缺陷会导致痛苦。白癜风是一种影响患者身体和社会心理功能的皮肤疾病。白癜风是一种慢性炎症性自身免疫性疾病,可导致表皮黑素细胞丢失,导致皮肤色素脱失和白斑的发生。白斑大小从几毫米到厘米不等。节段型和非节段型白癜风是白癜风的两种主要亚型。全球成人和年轻人白癜风的患病率估计为0.1-2%。节段型白癜风占全部白癜风病例的5-16%。中国白癜风患病率为0.54%,男性患病率(0.71%)高于女性(0.41%)。根据白癜风的特征性临床表现可直接诊断。除了皮肤特征外,心理社会特征,包括抑郁、广泛性焦虑障碍、睡眠问题、情绪和行为障碍以及社交恐惧症等,也是白癜风的重要问题。白癜风的重要诱发因素包括晒伤、压力、频繁的身体创伤、接触细胞毒性化合物和妊娠。皮肤在受到如划伤、摩擦等创伤后,可能会产生新的色素脱失性病变,这种现象称为Koebner现象。炎性白癜风、三色白癜风和碎纸屑样色素脱失是其特殊表现。白斑通常发生在面部、手足和前臂,还包括眼周和口周区域。目前认为白癜风是遗传和/或环境因素共同作用的结果,其发病部位的黑素细胞进行性减少。人们提出了几种理论来解释这种现象,包括自身免疫、神经激素失衡、遗传易感性、氧化应激、黑素细胞周围微环境的异常和内在异常,从而启动先天和适应性免疫的激活,进而导致黑素细胞破坏。近年来,白癜风被认为是一种自身免疫性疾病,可能与其他自身免疫性疾病(如1型糖尿病、自身免疫性甲状腺疾病、系统性红斑狼疮等)相关,其中自身免疫性甲状腺疾病最常见。然而,白癜风的确切病因仍不清楚。自身免疫和细胞毒性假说提出,白癜风黑素细胞破坏的主要原因可能是免疫系统监视的中断。研究表明,白癜风患者血液中存在针对黑素细胞抗原的循环反应性抗体。细胞免疫也被认为参与其中;皮损周围可见活化的CD8+T细胞和记忆性T细胞,导致黑素细胞破坏。干扰素γ对CD8+T细胞募集到病变部位起重要作用。因此,自身免疫紊乱成为白癜风最广泛接受的病因解释。白癜风治疗的主要目的是阻止疾病的进展和帮助复色。目前用于白癜风的主要治疗方法包括手术、Janus激酶抑制剂、光疗、外用皮质类固醇和外用钙调磷酸酶抑制剂等。手术通常只用于稳定期白癜风患者。已有研究调查白癜风对患者整体生活质量的影响。白癜风对中国患者生活质量影响的证据不足,尚无定论。本研究旨在调查中国白癜风患者的生活质量、对治疗的认知度和对治疗选择的满意度。此外,我们还通过评估白癜风治疗意愿(WTP)来确定疾病负担。方法:研究设计和参与者研究设计:本研究为非干预性横断面研究。研究对象为2021年3月至2022年8月在中南大学湘雅三医院(中国长沙)门诊就诊的白癜风患者。排除标准:(1)未确诊为白癜风的白癜风患者;(2)文盲或智力障碍;(3)因其他严重心理或躯体障碍无法填写问卷的白癜风患者;(4)不愿意接受调查评价。问卷由年龄大于18岁的患者填写,年龄小于18岁的患者由家属填写。我们对数据进行了识别和分类,以防止对参与者产生任何风险。我们向每位研究者提供了符合伦理的知情同意文件,以确保每位应答者均提供了知情同意书。本研究为横断面调查研究,经中南大学湘雅三医院伦理委员会批准。问卷:问卷包括4个部分的29个问题和其他信息:ⅰ.(Q1-Q11)白癜风患者的疾病信息和生活质量评估:(Q1)您第一次发现该病的年龄?(Q2)您的患病时间有多久?(Q3)您的白斑处在什么部位?(Q4)您近半年来的白斑情况变化是?(Q5)您的白斑分布情况?(Q6)您的白斑面积?(Q7)您在哪个季节第一次发现的白斑?(Q8)您是否合并有其他疾病?(Q9)您患有以下哪些疾病?(Q10)家族中其他直系亲属是否患有白癜风?(Q11)皮肤病学生活质量指数(DLQI/CDLQI)评分表ⅱ.(Q12-Q16)白癜风患者治疗现状及满意度评价:(Q12)您是否接受过治疗?(Q13)您接受了哪些治疗?(Q14)您接受治疗的时间有多长?(Q15)您的治疗效果如何?(Q16)您对当前治疗的满意度如何?ⅲ.(Q17-Q22)了解白癜风患者的疾病相关认知:(Q17,q1-q10)白癜风认知程度测试题:(q1)您认为白癜风是否具有传染性?(q2)您认为白癜风是遗传的吗?(q3)您认为白癜风是一种自身免疫性疾病吗?(q4)您认为您身上的白斑一定是白癜风吗?(q5)您认为白癜风患者是否应该多晒太阳?(q6)您认为白癜风患者不应食用维生素C吗?(q7)您认为白癜风可以完全治愈吗?(q8)您认
