Determination of the Protein-Protein Interactions within Acyl Carrier Protein (MmcB)-Dependent Modifications in the Biosynthesis of Mitomycin

open access: yesMolecules, 2021
Mitomycin has a unique chemical structure and contains densely assembled functionalities with extraordinary antitumor activity. The previously proposed mitomycin C biosynthetic pathway has caused great attention to decipher the enzymatic mechanisms for ...

On t-extensions of abelian groups [PDF]

open access: yes, 2014
Let G and C be two discrete abelian groups. It is known that Pext(C,G) is a subgroup of Ext(C,G). In this paper, we introduce the t-extensions of G by C. We will show that the set of all t-extensions of G by C is a subgroup of Ext(C,G) which contains Pext(C,G).

Analogues of hyperlogarithm functions on affine complex curves [PDF]

open access: yesarXiv, 2022
For $C$ a smooth affine complex curve, there is a unique minimal subalgebra $A_C$ of the algebra $\mathcal O_{hol}(\tilde C)$ of holomorphic functions on its universal cover $\tilde C$, which is stable under all the operations $f\mapsto \int f\omega$, for $\omega$ in the space $\Omega(C)$ of regular differentials on $C$.

Topical application of mitomycin-C in corrosive esophageal strictures

open access: yesJournal of Indian Association of Pediatric Surgeons, 2005
Introduction: Corrosive ingestion is the major cause of esophageal stricture in our country. Mitomycin-C, an anthracycline derived from Streptomyces caespitosus, has both antineoplastic and antiproliferative properties. Use of mitomycin-C have been well

Risk factors for the leakage of chemotherapeutic agents into systemic circulation after transcatheter arterial chemoembolization of hepatocellular carcinoma

open access: yesKaohsiung Journal of Medical Sciences, 2011
This prospective study was to investigate the possible risk factors for the leakage of chemotherapeutic agent into the systemic circulation after transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma (HCC).

The abc-conjecture is true for at least $N(c), 1 \leq N(c) <φ(c)/2$, partitions a, b of c [PDF]

open access: yesarXiv, 2003
We prove that for any positive integer c there are at least N(c), $1\leq N(c) < \phi(c)/2$ representations of c as a sum of two positive integers a, b, with no common divisor, such that the N(c) radicals R(abc) are all greater than kc, where k an absolute constant.

Several extremal problems on graphs involving the circumference, girth, and hyperbolicity constant [PDF]

open access: yesarXiv, 2020
To compute the hyperbolicity constant is an almost intractable problem, thus it is natural to try to bound it in terms of some parameters of the graph. Let $\mathcal{G}(g,c,n)$ be the set of graphs $G$ with girth $g(G)=g$, circumference $c(G)=c$, and $n$ vertices; and let $\mathcal{H}(g,c,m)$ be the set of graphs with girth $g$, circumference $c$, and $

Single-parton scattering versus double-parton scattering in the production of two $c \bar c$ pairs and charmed meson correlations at the LHC [PDF]

open access: yes, 2014
We compare results of exact calculations of single parton scattering (SPS) and double parton scattering (DPS) for production of $c \bar c c \bar c$ and for $D$ meson correlations. The SPS calculations are performed in collinear approximation with exact matrix element for $g g \to c \bar c c \bar c$ and $q \bar q \to c \bar c c \bar c$ subprocesses.

Comparison of single-drop mitomycin C regime with other mitomycin C regimes in pterygium surgery.

open access: yesIndian Journal of Ophthalmology, 2003
Purpose: To evaluate the safety and efficacy of single-drop instillation of mitomycin C (MMC) in pterygium surgery and to compare the results with both postoperative and intraoperative application of MMC.
