Halamphora minima An & Kim & Kang & Cho & Kim 2022, sp. nov.
No full textHalamphora minima sp. nov. S.M. An, J.H. Kim, N.S. Kang, K. Cho, J.A. Lee & E.S. Kim Description: The valves are semi-lanceolate with a convex dorsal margin and nearly straight ventral margin (Figs 2–10). The valve length is 5.6–7.4 μm and the breadth is 2.3–3.3 μm (n = 36, Table 1). The central area is expanded on the ventral side only and closed with striae near the valve margin (Fig. 11, 17; asterisk). The raphe is straight with straight distal raphe ending and lie along the ventral margin (Fig. 11). The raphe ledge is fairly well-developed to the dorsal side of the valve (Figs 11, 13, 17; arrow). An axial longitudinal line is not present on the dorsal side. Striae slightly radiate on the dorsal side, but ventral striae parallel to the center and slightly radiated towards the apices. The dorsal striae (27–29 in 10 μm) are biseriate throughout the valve (Table 1), composed of small round or ovoid areolae (Figs 11–15, 17), and are separated by strongly developed costa. The ventral striae are almost invisible under a LM. In SEM, the ventral striae (43–45 in 10 μm, n = 13, Table 1) are uniseriate and interrupted by a central nodule area (Figs 11, 17; asterisk). Internally, a single row of dorsal areolae close to the raphe is delimited by an internal longitudinal rib (Fig. 14; arrow). The dorsal striae and areolae are arranged in one row between the internal longitudinal rib and the raphe (Fig. 14). The areolae are occluded by hymens (Fig. 15; arrows). The fused helictoglossae of the internal proximal raphe endings are small and tongue-shaped (Fig. 14). The internal distal raphe endings terminate with poorly developed helictoglossae (Fig. 14; arrowhead). The girdle bands are numerous, and round or ovoid poroids are arranged in two rows of 44 – 47 in 10 μm on the dorsal side (Fig. 16). Type material: Intertidal mudflat in Hampyeong Bay (35º03’41.94’’ N, 126º24’40.06’’ E), Muan-gun, Jeollanamdo, Republic of Korea (site: HP2-2). Jul 19, 2018. Holotype: SEM stub no. MABIK DI00043438 (represented by the valve in Fig. 3 A) was deposited at the National Marine Biodiversity Institute of Korea (MABIK), Seocheon-gun, Chungcheongnam-do, Republic of Korea. Isotype: Slide no. MABIK DI00043439 and cleaned material MABIK DI00043440 (preserved in 100% ethanol). Etymology: The specific name, minima (Latin = very small, smallest), relates to the small size of this species. Distribution: Currently known only in type locality.Published as part of An, Sung Min, Kim, Jihoon, Kang, Nam Seon, Cho, Kichul & Kim, Eun Song, 2022, Halamphora minima (Catenulaceae, Bacillariophyta), new brackish diatom species from the mudflat in Hampyeong Bay, Korea, pp. 115-122 in Phytotaxa 572 (1) on pages 117-118, DOI: 10.11646/phytotaxa.572.1.9, http://zenodo.org/record/730575

Unimodality of Betti numbers for Hamiltonian circle actions with index-increasing moment Maps
No full textThe unimodality conjecture posed by Tolman in [L. Jeffrey, T. Holm, Y. Karshon, E. Lerman and E. Meinrenken, Moment maps in various geometries, http://www.birs.ca/workshops/2005/05w5072/report05w5072.pdf] states that if (M,ω) is a 2n-dimensional smooth compact symplectic manifold equipped with a Hamiltonian circle action with only isolated fixed points, then the sequence of Betti numbers {b0(M),b2(M),...,b2n(M)} is unimodal, i.e. bi(M) ≤ bi+2(M) for every i < n. Recently, the author and Kim [Y. Cho and M. Kim, Unimodality of the Betti numbers for Hamiltonian circle action with isolated fixed points, Math. Res. Lett. 21(4) (2014) 691-696] proved that the unimodality holds in eight-dimensional case by using equivariant cohomology theory. In this paper, we generalize the idea in [Y. Cho and M. Kim, Unimodality of the Betti numbers for Hamiltonian circle action with isolated fixed points, Math. Res. Lett. 21(4) (2014) 691-696] to an arbitrary dimensional case. We prove the conjecture in arbitrary dimension under the assumption that the moment map H : M → R is index-increasing, which means that ind(p) < ind(q) implies H(p) < H(q) for every pair of critical points p and q of H, where ind(p) is the Morse index of p with respect to H. © World Scientific Publishing Company1111sciescopu
Systems biology for reverse aging
No full textCellular senescence is an irreversible and permanent cell cycle arrest in response to internal and external stresses. Its unresponsiveness to growth factor signals distinguishes it from a potentially reversible state, quiescence. Cellular senescence can inhibit tumor development by blocking proliferation of damaged cells, but as senescent cells become accumulated in a tissue, they can contribute to the promotion of agerelated diseases such as cancer by secreting inflammatory cytokines [1]. © 2021 Cho et al.

The antihypertensive effects of the Jamaican Cho-Cho (Sechium edule)
No full textThe experiments reported in this study constitute a preliminary investigation into the possible hypotensive effect of the Jamaican Cho-Cho (Sechium edule). Experiments were conducted in a random and blind fashion on two sub species of Sechium edule. Both the pulp and the peel were examined for hypotensive activity. Water-soluble extracts were prepared from these components of the fruit and injected into anaesthetised rats. Various cardiovascular parameters were measured including heart rate, mean arterial pressure (MAP) and several ECG intervals. We report that all extracts tested produced a fall in blood pressure with little change in ECG intervals. Extract B produced the least change in heart rate with a fall in MAP of approximately 23 mmHg. Changes in heart rate with all extracts appeared to be minimal as an ED25 value could only be determined for extract A, and ED10 values could not be evaluated for extracts C and D. The mechanism(s) by which these extracts produce their hypotensive effects could not be determined in these preliminary experiments. However, it appears not to involve direct effects on cardiac tissue. This conclusion is based on the finding that it took a minimum of 10 to 15 seconds for the hypotensive action to manifest post bolus. Future experiments will be aimed at delineating the mechanism(s) involved in decreasing MAP.Peer reviewedfinal article publishe

The final version is available through the publisher’s platform.Chinese hamster ovarian cells (CHO) cells have been extensively utilized for industrial production of biopharmaceutical products, such as monoclonal antibodies, human growth hormones, cytokines, and blood-products. Recent advances in recombinant DNA technology have resulted in the bioengineering of CHO cells that have robust gene amplification systems and can also be adapted to grow in suspension cultures. In parallel, recent advances in techniques and tools for decoding the CHO cell genome, transcriptome, proteome, and glycome have led to new areas of study for better understanding the metabolic pathways in CHO cells with the long-term goal of developing new biologics. This review paper discusses the recent advances in bioengineering strategies in CHO cell lines and the impact of the knowledge gained by CHO cell genomics, transcriptomics, and glycomics on the future of CHO-cell engineering.National Institute of General Medical Scienceshttps://login.libproxy.rpi.edu/login?url=https://doi.org/10.1002/bit.2484
