Abstract
Lithium ion capacitors (LICs) are a new generation of energy storage devices that combine the super energy storage capability of lithium ion batteries with the satisfactory power density of supercapacitors. The development of high-performance LICs still faces great challenges due to the unbalanced reaction kinetics at the anode and cathode. Therefore, it is an inevitable need to enhance the electron/ion transfer capability of the anode materials. In this paper, to obtain a superior-rate and high-capacity Ni3S2-based anode, highly conductive Ti3C2Tx MXene sheets were introduced to sever as the carrier of Ni3S2 nanoparticles and simultaneously an amorphous carbon layer which coats onto the surface of Ni3S2 nanoparticles was in-situ generated by the carbonization of dopamine reactant. The as-synthesized Ni3S2/Ti3C2Tx/C composite exhibits a high specific surface area (112.6 m2/g) because of the addition of Ti3C2Tx that can reduce the aggregation of Ni3S2 nanoparticles and the in-situ generated amorphous carbon layer that can suppress the growth of Ni3S2 nanoparticles. The Ni3S2/Ti3C2Tx/C anode possesses a remarkable reversible discharge specific capacity (626.0 mAh/g under 0.2 A/g current density), which increases to 1150.8 mAh/g after 400-cycle charge/discharge measurement at the same measurement condition indicating eminent cyclability, along with superior rate capability. To construct a superior-performance LIC device, a sterculiae lychnophorae derived porous carbon (SLPC) cathode with an average discharge specific capacity of 73.4 mAh/g@0.1A/g was prepared. The Ni3S2/Ti3C2Tx/C//SLPC LIC device with optimal cathode/anode mass ratio has a satisfactory energy density ranging from 32.8 to 119.1 Wh kg-1 at the corresponding power density of 8799.4 to 157.5 W kg-1, together with a prominent capacity retention (95.5 %@1 A/g after 10,000 cycles).

Abstract
Ternary metal sulfides employed in supercapacitors exhibit better electrochemical performances than their counterpart oxides due to their superior conductivity. However, the insertion/extraction of electrolyte ions can lead to a significant volume change in electrode materials, which can result in poor cycling stability. Herein, novel amorphous Co-Mo-S nanospheres were fabricated through a facile room-temperature vulcanization method. It involves the conversion of crystalline CoMoO4 by reacting it with Na2S at room temperature. In addition to the conversion of the crystalline state into an amorphous structure with more grain boundaries, which is beneficial for the transport of electron/ion and can accommodate the volume change generated by the insertion/extraction of electrolyte ions, the production of more pores led to an increased specific surface area. The electrochemical results indicate that the as-prepared amorphous Co-Mo-S nanospheres had a specific capacitance of up to 2049.7F/g@1 A/g together with good rate capability. The amorphous Co-Mo-S nanospheres can be used as the cathode of supercapacitors and assembled with an activated carbon anode into an asymmetric supercapacitor possessing a satisfactory energy density of 47.6 Wh kg-1@1012.9 W kg-1. One of the prominent features exhibited by this asymmetric device is its remarkable cyclic stability, with a capacitance retention of 107% after 10,000 cycles.

Abstract
Objective: To investigate the clinical characteristics, response, and prognosis of splenic diffuse red pulp small B-cell lymphoma (SDRPL) . Methods: Eight cases of SDRPL were diagnosed and treated at Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, between May 2017 and April 2022. Data on the clinical features, laboratory results, bone marrow and spleen biopsy results, response, and prognosis were collected and analyzed. Results: The median age at diagnosis was 54 (42-69) years. Splenomegaly and lymphocytosis were present in all cases, and PET/CT revealed normal to slightly elevated splenic FDG uptake. All cases were in stage Ⅳ, with spleen, peripheral blood, and bone marrow but no proximal lymph nodes involved. The cytoplasm of neoplastic villous cells was abundant, and splenic pathology showed that small homogenous lymphocytes permeated the splenic sinus and splenic cord, and the white pulp atrophied. Immunohistochemistry was not typical, and B-cell markers including CD19, CD20 and CD79α were positive. After a median follow up of 35.5 (4-60) months, 7 cases were alive after splenectomy with or without chemoimmunotherapy. The patient with CCND3 P284A and MYC S146L mutation developed to B-cell prolymphocytic leukemia (B-PLL) 1 month after splenectomy and died at 16 months of follow-up. Conclusion: A rare indolent B-cell lymphoma that primarily affects the elderly, SDRPL. Most patients achieved long-term survival, but the prognosis of patients who progress to B-PLL was poor.

Abstract
Objective: To explore the effect and mechanism of peroxiredoxin1 (PRDX1) in epithelial mesenchymal transformation (EMT) of gastric cancer cells. Methods: The expression of PRDX1 protein was detected by immunohistochemistry (IHC) in 70 paraffin specimens of cancer and normal mucosa adjacent to gastric cancer, and the relationship between PRDX1 protein and clinicopathological characteristics was analyzed. Then PRDX1-small interfering RNA (siRNA) was synthetized and transfected into human gastric cancer cell line AGS, and 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H tetrazolium bromide (MTT) assay was used to test cell proliferation. Transwell chamber assay was employed to test invasion of cells. Real-time quantitative polymerase chain reaction (RT-qPCR) and western blot were utilized to test the expressions of PRDX1, E-cadherin, N-cadherin, vimentin, and claudin-1. Results: The positive rate of PRDX1 protein expression in gastric cancer was 81.4%, higher than that in normal mucosa (27.1%, P<0.05). The expression of PRDX1 protein was related to invasive depth and lymph node metastasis of gastric cancer (P<0.05). The expressions of PRDX1 mRNA and protein in AGS cells (2.216±0.445, 1.212±0.136), were higher than those in GES-1 cells (0.342±0.041, 0.328±0.038) (P<0.05). When PRDX1-siRNA was transfected into AGS cells, the proliferation of AGS cells was significantly inhibited (all P<0.05). The invasion and migration rate of AGS cells in the transfection group [(112.00±17.98), (50.87±9.79)%] were significantly lower than those of the negative control group [(192.50±22.02), (83.03±8.67)%] and blank control group [(193.83±22.40), (82.40±7.21)%] (all P<0.05). The expressions of mRNA and protein of N-cadherin, vimentin and claudin-1 decreased, while the expression of E-cadherin increased when PRDX1-siRNA was transfected into AGS cells (P<0.05). Conclusion: PRDX1 may promote the development of gastric cancer by regulating the EMT of gastric cancer cells.

Abstract
Objective: Biological behavior, pathological characteristics and prognostic factors of 355 cases with gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) were analyzed in this retrospective study. Methods: In our study, 355 patients pathologically diagnosed as GEP-NENs were identified from April 2006 to November 2017 in the Fourth Hospital of Hebei Medical University. The biological behavior, pathological characteristics and prognosis were analyzed retrospectively. Results: There were 355 patients (228 males and 127 females) with a mean age of 58.3±10.7 years. GEP-NENs were detected most frequently in the stomach (48.2%), followed by the pancreas (16.1%), colorectum (14.1%), esophagus (7.6%), duodenum/jejunum(5.6%), liver (4.2%), appendix (2.3%) and gallbladder/bile duct (2.0%). The main clinical manifestations of non-functional GEP-NENs were abdominal pain (88/350, 25.14%), ventosity (77/350, 22.00%) and dysphagia (68/350, 19.43%), which were generally lacking specificity at the first diagnosis. 295 patients were treated surgically, including 45 cases of endoscopic resection and 250 cases of laparoscopic operation. Concerning to pathological grading, there were 22.5% (80/355) patients in grade 1 (G1), 12.7% (45/355) in grade 2 (G2), and 58.9% (209/355) in grade 3 (G3). The median follow-up time was 34 months. Furthermore, the 1-, 3- and 5-year overall survival calculated by Kaplan-Meier method were 80.1%, 59.8%, and 57.5%, respectively. Univariate analysis revealed that tumor site, treatment, operation type, depth of tumor invasion, TNM staging, pathological grading, vascular embolus, lymph node metastasis, tumor size, preoperative leukomonocyte level and preoperative plasma albumin were associated with overall survival (all P<0.05). Multivariate analysis showed that treatment, operation type, depth of tumor invasion, TNM staging, pathological grading, vascular embolus, lymph node metastasis and tumor size were independent prognostic factors for GEP-NENs (all P<0.05). Conclusions: The clinicopathological characteristics of GEP-NENs should be mastered by clinicians, and the standard treatment measures were also needed to be formulated based on the prognostic factors in order to improve the prognosis of patients.

Abstract
Objective: To explore the clinical significance of laparoscopic exploration combined with abdominal exfoliative cytology in the diagnosis and treatment of patients with locally advanced gastric cancer. Methods: Inclusion criteria: (1) cancer confirmed by gastroscopy and pathology without preoperative anti-tumor treatment; (2) no distant metastases found in preoperative imaging examinations; (3) patients without surgical contraindications and being tolerant to surgery; (4) patients were willing to undergo laparoscopic exploration and abdominal exfoliative cytology examination, and signed informed consent. A retrospective cohort study method was used to collect and analyze the clinicopathological data of 225 patients with advanced gastric cancer based on the above inclusion criteria from a prospective, multicenter, open, randomized controlled phase III clinical trial (registration No. NCT01516944) conducted between February 2012 and December 2018 in The Fourth Hospital of Hebei Medical University, including 162 males and 63 females with age ranged from 23 to 78 years old. Forty-five patients (20.0%) were classified as Borrmann type I to II, and 180 (80.0%) were classified as type III to IV. All the patients underwent laparoscopy and peritoneal lavage cytology under general anesthesia. Laparoscopic exploration sequence: left and right diaphragm→liver and spleen→parietal peritoneum→pelvic cavity→greater omentum, small intestine, mesentery→transverse colon mesentery →stomach. Contents of exploration: (1) with or without ascites; (2) whether metastatic lesions existed in the peritoneum, mesentery, omentum and Douglas pouch; (3) whether metastasis existed on the liver surface; (4) whether the gastric lymph nodes were swollen; (5) whether infiltration occurred on the gastric serosa surface; (6) whether gastric wall was stiff. The left and right subphrenic, the abdominal and pelvic peritoneum, and the mesentery were rinsed with 500 ml of sterilized normal saline. Position of the reverse Trendelenburg was used in the Douglas pouch. The peritoneal lavage fluid under the liver and spleen fossa was collected. Cytological examination was carried out for exfoliative tumor cells. Evaluation criteria: (1) peritoneal metastasis (P): P0 meant no peritoneal metastasis, P1 meant peritoneal metastasis; (2) free peritoneal cancer cells (CY): CY0 meant no cancer cells in peritoneal lavage fluid cytology, CY1 meant cancer cells in peritoneal lavage fluid cytology. The results of patients undergoing laparoscopic exploration combined with abdominal exfoliative cytology, treatment options and prognosis were analyzed. Kaplan-Meier method was used to calculate the survival rate and a survival curve was drawn. Log-rank test was used for survival analysis. Results: After laparoscopic exploration in 225 patients, clinical staging was corrected in 68 (30.2%) patients, of whom 7 (3.1%) downstaged and 61 (27.1%) increased in staging. Of 164 patients evaluated as P0CY0 after the first laparoscopy and peritoneal cytology examination, 126 underwent radical D2 surgery, and the other 38 patients were found to have later local lesions or extensive fusion of local lymph nodes, so then received neoadjuvant chemotherapy. Twenty-nine patients evaluated as P1CY0 or P1CY1 and 32 patients as P0CY1 underwent intraperitoneal hyperthermic chemotherapy+conversion therapy, and then a second laparoscopic exploration was performed to determine the treatment plan. In total, the original treatment regimens were changed after laparoscopic exploration in 99(44.0%) cases. The follow-up period ended in January 2019. The overall 2-year survival rate of 225 patients was 64.0%. As for those who were evaluated as P0CY0, P0CY1 and P1CY0-1 after the first laparoscopic exploration, the 2-year overall survival rate was 70.7%, 65.6% and 24.1%, respectively (P=0.002). The stratified analysis showed that among 180 patients with stage III tumor, after laparoscopic exploration combined with abdominal exfoliative cytology, 125 patients were found to be P0CY0, 28 were P0CY1, and 27 were P1CY0-1, whose 2-year overall survival rates were 70.4%, 64.3%, and 29.6% respectively, and the difference among these 3 groups was statistically significant (P=0.009). Conclusion: Laparoscopic exploration combined with abdominal exfoliative cytology in patients with locally advanced gastric cancer has important clinical guiding significance in improving accurate staging, treatment options and prognosis evaluation, and can avoid non-therapeutic open-close abdominal surgery.

Abstract
BACKGROUND The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China. METHODS This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used. RESULTS Although erratic changes were observed in the median semen parameters (sperm concentration 40.1-52.1 × 106/ml, total sperm count 117.8-153.1 × 106, sperm progressive motility 33.4-38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men showed normal semen parameters according to the World Health Organization (WHO) criteria. According to the joinpoint regression analysis, sperm progressive motility appeared to decrease earlier than the sperm concentration and total sperm count (at 28, 58, and 42 years of age, respectively). CONCLUSIONS There is no evidence of a deterioration in semen quality among infertile men in Hunan, China. Semen parameters decreased with increasing age, with turning points noted at different ages. Semen parameters are not absolute evidence for the assessment of male fertility potential. Therefore, we believe that, among semen parameters, the sperm concentration is the best predictor of fertility for ART, followed by motility. Decreased sperm motility may affect natural pregnancy, but it is not necessary for successful IVF.

Abstract
Gastric cancer (GC) is a leading cause of global cancer-related death. The incidence and mortality rates of gastric cancer in China are second and third ranked in all forms of malignant tumors. Krüppel-like factor11 (KLF11) is a member of the KLF family, and previous studies have shown it significantly influences epithelial ovarian, pancreatic and liver cancer proliferation, differentiation and apoptosis. However, the expression and some biological functions of KLF11 in GC are still unclear. We therefore collected and analyzed the mRNA and protein expressions of KLF11 in 59 paired gastric cancer tissues and matched healthy gastric tissue samples. We then investigated the KLF 11 biological functions and potential mechanisms in BGC823 and HGC27 gastric cancer cell lines. Analysis of KLF11 in gastric cancer specimens confirmed up-regulation compared to adjacent healthy gastric tissues, and similar results were evident in the GC cell lines. Ectopic expression of KLF11 was significantly associated with GC cell invasion and migration. KLF11 functions were most effective in Twist1 expression and knockdown, and also in KLF11 up-regulation which was accompanied by corresponding change in Twist1 expression; but these effects were inhibited when KLF11 was silenced by the small interfering RNA (siRNA). The relative Twist1 promoter region activity increased gradually with increasing KLF11 plasma, and KLF11 therefore has a critical role in regulating gastric cancer migration and invasion by increasing Twist1 expression. Finally, the results of this study should improve understanding of the KLF11 and EMT regulating network and KLF11's use as a potential therapeutic target in gastric cancer.

Abstract
Co@NiSe₂ electrode materials were synthesized via a simple hydrothermal method by using nickel foam in situ as the backbone and subsequently characterized by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and a specific surface area analyzer. Results show that the Co@NiSe₂ electrode exhibits a nanowire structure and grows uniformly on the nickel foam base. These features make the electrode show a relatively high specific surface area and electrical conductivity, and thus exhibit excellent electrochemical performance. The obtained electrode has a high specific capacitance of 3167.6 F·g-1 at a current density of 1 A·g-1. To enlarge the potential window and increase the energy density, an asymmetric supercapacitor was assembled by using a Co@NiSe₂ electrode and activated carbon acting as positive and negative electrodes, respectively. The prepared asymmetrical supercapacitor functions stably under the potential window of 0⁻1.6 V. The asymmetric supercapacitor can deliver a high energy density of 50.0 Wh·kg-1 at a power density of 779.0 W·kg-1. Moreover, the prepared asymmetric supercapacitor exhibits a good rate performance and cycle stability.

Abstract
Semen analysis is used for diagnosing male infertility and evaluating male fertility for more than a century. However, the semen analysis simply represents the population characteristics of sperm. It is not a comprehensive assessment of the male reproductive potential. In this study, 20 semen samples from human sperm bank with distinctive artificial insemination with donor sperm (AID) clinical outcomes were collected and analyzed using a two-dimensional differential in-gel electrophoresis (2D-DIGE); 45 differentially expressed protein spots were obtained, and 26 proteins were identified. Most differentially expressed proteins were related to sperm motility, energy consumption, and structure. These identified proteins included several sperm proteins associated with the nucleus on the X chromosome (SPANX) proteins. This prospective study aimed to investigate the association between the expression levels of SPANX proteins and the AID clinical outcomes. The proteins identified in this study provided a reference for the molecular mechanism of sperm fertility and revealed a predictive value of the SPANX proteins.

Abstract
Objective: To investigate the effect of postoperative precision nutrition therapy on postoperative recovery (PR) of patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NC). Methods: 71 subjects were randomly divided into 2 groups. The 34 patients of research group were treated with postoperative precision nutrition treatment according to the indirect energy measurement method. The 31 patients of control group were treated with traditional postoperative nutrition treatment. All participants were measured for body mass index (BMI), NRS2002, PG-SGA and relevant laboratory test within the 1st day before surgery and 7th day after surgery. Moreover, the difference between two groups in short-term effects were evaluated. Results: The daily energy supply of control group was 30.1%-43.74% higher than that of the experimental group (P<0.05). The resting energy expenditure (REE) of the research group after surgery was lower than that before operation. The levels of prealbumin, albumin and lymphocyte count were higher in research group than the controls at the 7th day after surgery whereas the opposite was true for the creatinine, urea nitrogen, C-reactive protein and procalcitonin (P<0.05). Similarly, the rate of malnutrition and nutritional risk became lower in the research group (P<0.05). The gastrointestinal function recovery of patients in the research group was comparable to that of the control group (P>0.05). Moreover, the complication rate and hospitalization costs of in research group were significantly lower than that of in control group (P<0.05). For patients with or without nutritional risks before surgery, the nutritional index and inflammatory index in the research group were better than those in the control group. Conclusion: Postoperative precision nutrition therapy may improve the postoperative nutritional status and short-term effects of patients with AGC after NC.

Abstract
OBJECTIVE To investigate the expression of annexin A7 (ANXA7) in the differentiation and lymphatic metastasis of gastric cancer (GC), and to investigate the relationship between ANXA7 and biological characteristics of GC. METHODS The clinicopathological data of 124 patients with gastric cancer who underwent surgical treatment in our hospital were retrospectively reviewed and analyzed. Immunohistochemical staining and Western blot were performed to analyze the expression of ANXA 7 in primary GC tissues. Logistic regression analysis was conducted to evaluate the association between ANXA7 expression level and differentiation of the GC. RESULTS A total of 124 GC patients were enrolled in this study, and the expression rate of ANXA7 was 65.3% in the GC. The survival rate of ANXA7-positive patients was significantly lower than that in the patients with negative expression (P<0.001). The results of Cox regression analysis showed that the positive expression of ANXA7, submucosal confinement and pathological stage of GC were associated with poor clinical outcomes. The ratio of pixel density value of primary GC tissues with lymph node metastasis was significantly higher than those in the tissues without lymph node metastasis (0.51±0.07 vs. 0.39±0.06, P<0.001). ROC analysis showed a high area under the curve for the ratio of pixel density value of annexin A7 in the primary GC tissues. At a cut-off level of >0.419, the ratio of pixel density value of ANXA7 exhibited a sensitivity of 91.2% and a specificity of 72.7% for detecting lymph node metastasis of GC. CONCLUSION High annexin A7 expression is associated with poor differentiation of gastric cancer, and it may become a predictor for lymphatic metastasis of GC.

Abstract
Zinc finger protein 139(ZNF139), a member of zinc finger protein family, is a transcription factor. Our previous research showed ZNF139 was overexpressed in gastric cancer cells. The purpose of present study is to explore impact and mechanism of ZNF139 on metastasis by regulating invasive ability of gastric cancer cells. Quantitative RT-PCR(QRT-PCR) and Western blot were applied for detection of ZNF139 expression in gastric cancer tissues, adjacent cancer tissues, metastatic lymph nodes, gastric cancer cell lines SGC7901 and BGC823 and gastric epithelial cell line GES-1; siRNA specific to ZNF139 was synthesized and then transfected into gastric cancer cell line BGC823; wound healing assay and Transwell assay were used to observe impact of ZNF139-siRNA after being transfected into BGC823 on its invasion and migration; changes in expression of invasion and migration-related genes MMP-2, MMP-9, ICAM-1 and TIMP1 were detected before and after transfection. Gelatin zymogrphy assay were applied to determine the MMP activities. Statistical analysis was based on the SPSS11.5 software.Expression of ZNF139 in gastric adenocarcinoma tissues and cells was significantly higher than the expression in the adjacent cancer tissues, but lower than the expression in the metastatic lymph nodes; ZNF139 expression was present in gastric cancer cell lines, and the expression level was higher than that in normal gastric epithelial cells lines. ZNF139-siRNA significantly inhibited the invasion and migration activity of gastric cancer cell line BGC823. 48h after ZNF139-siRNA was transfected into gastric cancer cell line BGC823, expression and activity of invasion-related genes MMP-2, MMP-9, ICAM-1 mRNA and protein were significantly inhibited, while expressions of TIMP-1 mRNA and protein were significantly increased. At the same time, the gelatinase activities of MMP2 and MMP9 were decreased by ZNF139 interference.ZNF139 was overexpressed in gastric cancer cells, and the expression was further enhanced in the metastasis process. Knocking down ZNF139 expression in gastric cancer cells could effectively reduce gastric cancer cell invasion and migration ability, and this process might play a role by regulating MMP-TIMP balance.

Abstract
Annexin A3 participates in various biological processes, including tumorigenesis, drug resistance, and metastasis. The aim of this study was to investigate the expression of Annexin A3 in gastric cancer and its relationship with cell differentiation, migration, and invasion of gastric cancer cells. Annexin A3 expression in gastric cancer tissues was detected by quantitative real-time PCR and Western blotting. The proliferation of gastric cancer cells was measured by the MTT assay. Cell migration and invasion were determined via wound healing and transwell assays, respectively. Knock down of endogenous Annexin A3 in gastric cancer BGC823 cells was performed using siRNA technology. The expression of Annexin A3 was significantly upregulated in gastric cancer tissues, and negatively correlated with the differentiation degree. Silencing of endogenous Annexin A3 suppressed the proliferation, migration, and invasion of BGC823 cells. Additionally, the expression of p21, p27, TIMP-1, and TIMP-2 was upregulated, and the expression of PCNA, cyclin D1, MMP-1, and MMP-2 decreased in cells treated with Annexin A3-siRNA. Annexin A3 was upregulated in gastric cancer cells. Deletion of endogenous Annexin A3 significantly inhibited gastric cancer cell proliferation, migration, and invasion.

Abstract
The aim of this study was to assess the correlation of sperm morphology with the intrauterine insemination (IUI) outcome in patients with normal sperm concentration and motility. About 412 couples who underwent 908 IUI cycles were involved in the present study. A total of 110 clinical pregnancies were achieved with a pregnancy rate of 12.11% per cycle. The pregnancy rates per cycle were 7.60%, 12.67%, 13.62% and 13.13% in patients with <5%, 5-9%, 10-14% and >14% normal forms, respectively. The lowest pregnancy rate (7.60%) was obtained in the group with normal forms below 5%. However, this rate was not significantly different from other subgroups. Moreover, no pregnancies occurred in women >35 years old with normal sperm forms below 5%, in comparison with that in other subgroups of the same age. For women younger than 35 years old, no significant difference in pregnancy rate was observed in terms of different level of morphologically normal sperm. Our results show that for patients with normal sperm concentration and motility, IUI is recommended for first-line treatment when the woman is younger than 35 years, or morphologically normal sperm is ≥ 5%. IVF/ICSI should be performed when the normal forms are <5% and female age is > 35 years.

Abstract
In the title compound, {[Ag(2)Gd(C(6)H(4)NO(2))(4)(H(2)O)(2)]NO(3)·H(2)O}(n), the Gd(III) ion is coordinated by eight O atoms from six isonicotinate ligands and two water mol-ecules in a distorted square anti-prismatic geometry. Two Ag(I) ions are each bonded to two N atoms from two isonicotinate ligands in a linear or bow-like fashion [N-Ag-N angles = 178.6 (2) and 147.1 (2)°]. These metal ions are connected by the isonicotin-ate ligands into a layer parallel to (010). O-H⋯O hydrogen bonds donated by the coordinated and uncoordinated water mol-ecules and intra-layer π-π stacking inter-actions between the pyridine rings [centroid-centroid distances = 3.551 (4) and 3.555 (4) Å] are observed. The layers inter-act with each other by inter-layer Ag⋯O(aqua) contacts [2.731 (4) Å] and π-π stacking inter-actions between the pyridine rings [centroid-centroid distances = 3.466 (3) and 3.516 (3) Å], resulting in the formation of a three-dimensional supra-molecular structure.

Abstract
In the title coordination polymer, [La2(C8H4O4)3(H2O)2]n, there are two independent LaIII atoms which are coordinated differently in slightly distorted pentagonal-bipyramidal and slightly disorted bicapped trigonal-prismatic environments. The LaIII ions are bridged by μ4-isophthalate ligands, forming two-dimensional layers. In the crystal structure, these layers are connected by intermolecular O—H⋯O hydrogen bonds into a three-dimensional network.

Abstract
OBJECTIVE To establish the method of 2-dimensional electrophoresis(2-DE) for proteins of human spermatozoa and to construct a protein map of human spermatozoa. METHODS The sperm pellet was prepared with simple Percoll layer protocol. We studied the effects of various sample preparation methods, loading quantities and isoelectric-focusing protocols on the quality of silver-stained 2-DE map, and constructed a primary protein map of human spermatozoa. RESULT Up to 703 protein spots were acquired with sample preparation Method I while only 194-210 spots with Method II. With immobilized pH gradients and sodium dodecyl sulfate-polyacrylamide gel electrophoresis(IPG-DALT) we could acquire over 700 spots while only 280-300 with isoelectric focusing and sodium dodecyl sulfate-polyacrylamide gel electrophoresis(ISO-DALT). CONCLUSION It is satisfactory to lyse sperm with sample preparation Method I and to separate sperm proteins by IPG-DALT for establishing 2-D map of human sperm.
