The first structural determination of a copper (II) complex containing the ligand [1-(4-((1H-benzo[d][1,2,3]triazol-2(3H)-yl)methyl)benzyl)-1H-benzo[d][1, 2,3]triazole]

The reaction of the ligand [1-(4-((1H-benzo[d][1,2,3]triazol-2(3H)-yl)methyl)benzyl)-1H-benzo[d][1, 2,3]triazole] (L) with CuCl2 in acetonitrile yields a dinuclear copper(II) complex [Cu2Cl4L2]center dot 2CH(3)CN (1.2CH3CN), which has been characterized by elemental analysis, powder and single crystal X-ray diffraction, thermal gravimetric analysis as well as IR, UV-Vis and EPR spectroscopy The crystal structure reveals that the metal coordination geometry is best described as square planar.

Supramolecular networks derived from hexacyanoferrates and nitrogen heterocyclic cations

Eight novel supramolecular frameworks (bpyH2)2[Fe(CN)6]·2H2O (1), (bpyH2)(H3O)[Fe(CN)6] (2), (bpeH2)(H3O)[Fe(CN)5(CNH)]·H2O (3), (bpeH2)(H5O2)[Fe(CN)6]·2H2O (4), (dabcoH2)(H3O)[Fe(CN)6]·2H2O (5), (ampyH2)2[Fe(CN)6]·2H2O (6), (tptzH3)2[Fe(CN)4(CNH)2]3·10H2O (7), and (tptzH3)[Fe(CN)6]·3H2O (8) (where bpy = 4,4′-bipyridine, bpe = 1,2-bis(4-pyridyl)ethylene, dabco = 1,4-diazabicyclo[2.2.2]octane, ampy = 4-aminomethylpyridine, tptz = tris(4-pyridyl)triazine) have been synthesized by the reaction of the nitrogen heterocycle with ferrocyanide or ferricyanide salts, under mild conditions. The supramolecular structures are constructed mainly by cooperative hydrogen bonding between the inorganic anions, the organic cations and oxoniums or lattice water molecules. There are some characteristic features that can separate the compounds in groups. Those are (a) increase of H-bonding ability by formation of supramolecular complexes, (b) formation of hydro- and dihydro-hexacyanoferrates and (c) the participation of the cationic heterocycle as constituent of the structure or as a guest. The structures are additionally discussed in terms of topology

Multi-Port Robotic-Assisted Laparoscopic Myomectomy: A Systematic Review and Meta-Analysis of Comparative Clinical and Fertility Outcomes

Background: Uterine fibroids are the most frequently diagnosed gynaecological tumours, and they often require surgical treatment (conventional laparoscopic myomectomy—CLM). The introduction and evolution of robotic-assisted laparoscopic myomectomy (RALM) in the early 2000s has expanded the range of minimally invasive options for the majority of cases. This study aims to compare RALM with CLM and abdominal myomectomy (AM). Methods and materials: Fifty-three eligible studies adhered to the pre-established inclusion criteria and were subsequently evaluated for risk of bias and statistical heterogeneity. Results: The available comparative studies were compared using surgical outcomes, namely blood loss, complication rate, transfusion rate, operation duration, conversion to laparotomy, and length of hospitalisation. RALM was significantly superior to AM in all assessed parameters other than operation duration. RALM and CLM performed similarly in most parameters; however, RALM was associated with reduced intra-operative bleeding in patients with small fibroids and had lower rates of conversion to laparotomy, proving RALM as a safer overall approach. Conclusion: The robotic approach for surgical treatment of uterine fibroids is a safe, effective, and viable approach, which is constantly being improved and may soon acquire widespread adoption and prove to be superior to CLM in certain patient subgroups

The impact of coronavirus disease 2019 pandemic on female patients seeking or undergoing fertility treatment in a single In vitro Fertilisation clinic in greece: An international, cross-sectional study

Background: The temporary delay in fertility treatments due to the coronavirus disease 2019 (COVID-19) pandemic, in combination with the imposed lockdowns, has created psychological distress and anxiety amongst infertile patients. Aims: The aim of this study was to evaluate how the pandemic has influenced assisted reproduction technology (ART) patients in Greece, during the second wave of the pandemic. An additional aim was to examine the effects of the pandemic on cross-border patients in particular, compared to national ones. Settings and Design: This study was a cross-sectional, questionnaire-based study, distributed to 409 patients of a single in vitro fertilisation (IVF) clinic in Greece, during the period between January until the end of April 2021. Materials and Methods: The survey was conducted online via E-mail and was distributed to national and international female patients of a single IVF clinic in Greece, who were undergoing ART treatment during the second wave of the COVID-19 pandemic. Patient participation was anonymous, and participants provided informed consent for collection and publication of data. Statistical Analysis Used: The mean values of baseline characteristics, along with answer percentages per questionnaire item, were calculated. Collected data were cross-tabulated, and the Chi-square test was used as a measurement of the differences between national and cross-border patients. A P value lower than 0.05 was considered statistically significant. All analyses were conducted using the SPSS Statistics software. Results: From 409 initial candidates, 106 women, with a mean age of 41.2 years, completed the questionnaire (26% response rate). The majority of national patients did not experience any delays in their fertility plans (62%), while cross-border patients experienced over 6 months of delays (54.7%). The main reason for fertility postponement was travel restrictions due to COVID-19 for cross-border patients (62.5%), while national patients cited additional reasons. The majority of patients experienced a degree of stress (65.2%) due to the delays, however were not fearful of COVID-19 infection (54.7%). Most patients were aware of the protective measures taken by IVF clinics (80.2%), and this was a determinant factor (71.7%) for their decision to restart their fertility treatment. Conclusion: The COVID-19 pandemic lockdowns had a significant emotional impact on patient receiving or undergoing ART treatment in Greece. This impact was more pronounced on cross-border patients. This highlights the need for continuation of ART care, with the appropriate protective measures, during the pandemic, as well as during similar times of crisis in the future
