Due to enthralling applications in various fields and augmenting fundamental wisdom, π-conjugated macrocycles in general and porphyrin systems in particular are constantly explored. Subtle modifications of porphyrin structure can amend the rudimentary properties. Pursuing innovative properties provides impetus to underpin arene or pyridine moiety embedded porphyrin derivatives. There have been several reviews related to arene incorporated carbaporphyrinoids; however, recent developments of porphyrin analogues by introducing higher analogues of arenes and pyridine units are not adequately inspected. This mini-review mainly focuses on biphenyl, bipyridine, terphenyl, and mixed arene pyridine embedded porphyrin analogues and their coordination chemistry.The integration of simple components to generate sophisticated hybrid materials with fine-tuned properties represents a significant scientific challenge. Herein, we present recent advances in the use of polymers to control the synthesis and properties of three of the most relevant inorganic nanoparticles, namely, quantum dots (QDs), magnetic nanoparticles (MNPs), and noble metal nanoparticles (NMNPs). We show relevant examples of how polymeric structures synthesized by techniques such as ATRP, RAFT, and living cationic polymerization are used to aid in the synthesis and stabilization of the nanostructures to generate nanocomposites with outstanding capabilities. Special emphasis is placed on describing how some of the exceptional physicochemical properties of polymers are used as nanoreactors to facilitate the synthesis of the nanostructure by providing an adequate chemical environment. Additionally, we also describe how polymers are utilized to protect the integrity of the nanostructure from chemical degradation. The integration of polymeric structures and the nanostructures has a strong impact on the dispersion and morphology of the latter and, consequently, endow them with novel and promising features. The advances described here, particularly the use of polymers to modulate and provide new properties to nanoparticles, exemplify the great versatility of polymers and how these may expand the capabilities of inorganic nanostructures that can be used to generate novel and sophisticated hybrid materials.The transformation of silica (SiO2) to useful chemicals is difficult to explore because of the strength of the Si-O bond and thermodynamic stability of the SiO2 structure. The direct formation of alkoxysilanes from SiO2 has been explored as an alternative to the carbothermal reduction (1900 °C) of SiO2 to metallic silicon (Simet) followed by treatment with alcohols. The base-catalyzed depolymerization of SiO2 with diols and monoalcohols afforded cyclic silicon alkoxides and tetraalkoxysilanes, respectively. SiO2 can also be converted to alkoxysilanes in the presence of organic carbonates, such as dimethyl carbonate. Alkoxysilanes can be further converted to useful chemicals, such as carbamates, organic carbonates, and chlorosilanes. An interesting and highly efficient pathway to the direct conversion of SiO2 to alkoxysilanes has been discussed in detail along with the corresponding economic and environmental implications. The thermodynamic and kinetic aspects of SiO2 transformations in the presence of alcohols are also discussed.This Mini-Review highlights the most effective protocols for metal-free direct synthesis of imidazo[1,2-a]pyridines, crucial target products and key intermediates, developed in the past decade. The emphases is given on the ecological impact of the methods and on the mechanistic aspects as well. The procedures efficiently applied in the preparation of important drugs and promising drug candidates are also underlined.Furfural (FF) and 5-(hydroxymethyl)furfural (HMF) are well-recognized biomass-derived chemical building blocks with established applications and markets for several of their derivatives. Attaining a wide spectrum of petrochemicals is the primary target of a biorefinery that employs FF and HMF as the chemical feedstock. In this regard, cyclopentanone (CPN) is a crucial petrochemical intermediate used for synthesizing a diverse range of compounds with immense commercial prospects. The hydrogenative ring rearrangement of FF to CPN in an aqueous medium under catalytic hydrogenation conditions was first reported in 2012, whereas the first report on the catalytic conversion of HMF to 3-(hydroxymethyl)cyclopentanone (HCPN) was published in 2014. Cefodizime in vitro Over the past decade, several investigations have been undertaken in converting FF and HMF to CPN and HCPN, respectively. The research studies aimed to improve the scalability, selectivity, environmental footprint, and cost competitiveness of the process. A blend of theoretical and experimental studies has helped to develop efficient, inexpensive, and recyclable heterogeneous catalysts that work under mild reaction conditions while providing excellent yields of CPN and HCPN. The time is ripe to consolidate the data in this area of research and analyze them rigorously in a review article. This work will assist both beginners and experts of this field in acknowledging the accomplishments to date, recognize the challenges, and strategize the way forward.
The relative refractory period (RRP) of motor axons is an important parameter in nerve excitability tests of the recovery cycle (RC). Abnormalities may have a site in the axonal membrane, the neuromuscular junction, or in a dysfunction of the muscle. We aimed in this study to determine the site of abnormality, using a modified protocol of the conventional RC test, whereby an additional supramaximal stimulus is added at the same interstimulus interval as in RC recordings (RCSM).

Twenty-four healthy subjects aged 37.8 ± 2.4 years (mean ± SE) were examined with median nerve excitability testing using RC and RCSM protocols at normal temperature (34.1 ± 0.2 °C). The recordings were repeated in 12 subjects after selective cooling of the thenar muscle (25.2 ± 0.7 °C) and in 12 subjects after cooling the nerve trunk at the wrist (24.9 ± 0.3 °C).

After cooling the nerve, RRP measured with RC and RCSM were prolonged similarly (medians by 1.8 ms, and 2.1 ms respectively). In contrast, cooling the muscle prolonged RRP measured with RC (by 1.3 ms), but did not significantly prolong RRP measured with RCSM. RRPs measured by RC and RCSM were significantly different when cooling was at the muscle (P = 5.10
), but not when cooling was at the nerve (P = 0.57).

A difference between RC and RCSM indicates abnormal excitability distal to the axonal membrane under the stimulating electrode.

Combining RCSM with the conventional RC protocol should help to localize the site of abnormal neuromuscular refractoriness.

To report the impact of Rho-Associated Kinase Inhibitor Eye Drops in cases of cataract surgery performed in severe Fuchs' endothelial corneal dystrophy (FECD).

A patient affected by FECD stage II underwent femtosecond laser-assisted cataract surgery (FLACS), developed postsurgical corneal failure and was scheduled for endothelial keratoplasty. Compassionate treatment with Rho-Associated Kinase Inhibitor Eye Drops 4 times per day was started. A significant improvement in visual acuity and corneal failure was recorded. Thereafter, other two patients affected by FECD stage II were prophylactically treated with Rho-Associated Kinase Inhibitor Eye Drops 4 times per day for three months before FLACS with good visual and clinical outcome.

These cases expand upon the reported effects of rho-associated kinase inhibitor Ripasudil in the FECD, suggesting a role as adjuvant medical therapy in patients advised for intraocular surgery to improve endothelial function and reduce the risk of pseudophakic bullous keratopathy (PBK).

To report the efficacy of anti-tumor necrosis factor α (anti-TNFα) on autoimmune-mediated macular cone dysfunction in a Japanese woman with ulcerative colitis (UC).

A 41-year-old woman presented with bilateral visual acuity loss and photophobia. She suffered from UC, and had been treated with prednisolone and 5-aminosalicylate since age 37. Although fundus photographs and optic coherence tomography images were unremarkable, electroretinograms (ERGs) were abnormal. A full-field electroretinogram (full-field ERG) revealed mildly decreased cone responses and oscillatory potential responses bilaterally. Importantly, focal-macular ERG (fmERG) and a multifocal electroretinogram (mfERG) revealed severe macular cone dysfunction in both eyes. Infliximab, a chimeric monoclonal anti-TNFα antibody, was administrated to treat recurrent abdominal symptoms and continued at 8-week intervals. Almost 6 months after infliximab therapy, the mfERG response (especially in the central retina), the fmERG response, and visual acuity recovered bilaterally. Abdominal symptoms also improved after infliximab therapy.

Bilateral cone dysfunction with normal fundus were observed in a UC patient, resulting in loss of visual acuity and photophobia. This retinopathy may have been caused by an autoimmune mechanism, such as an autoimmune retinopathy or acute zonal occult outer retinopathy, which is most identifiable by ERG changes. This is the first report demonstrating the efficacy of infliximab in autoimmune retinal dysfunction.

Most of the previously mapped subsurface structures in the region under consideration focus on delineating crustal structures thicknesses and Moho depths undulations. Moreover, surface structures in the same region were mapped using analysis of Digital Elevation Model image data. On the other hand, there are few studies that have targeted in mapping geologic structures lying at depth levels between the shallower and deeper subsurface. The objective of this research is thus to map the subsurface geologic structures/lineaments to an average depth of 3 km (crystalline basement layer depth) from surface using gravity data. These investigation results are validated by Digital Elevation Model extracted lineaments. Filtering techniques including derivative filters, upward-continuation and line module algorithm of PCI Geomatica are used to extract the Ethiopian rift.
