Graphically balanced equilibria and stationary measures of reaction networks
No full textThe graph-related symmetries of a reaction network give rise to certain special equilibria (such as complex balanced equilibria) in deterministic models of dynamics of the reaction network. Correspondingly, in the stochastic setting, when modeled as a continuous time Markov chain, these symmetries give rise to certain special stationary measures. Previous work by Anderson, Craciun, and Kurtz [Bull Math. Biol., 72 (2010), pp. 1947-1970] identified stationary distributions of a complex balanced network; later, Cappelletti and Wiuf [SIAM J. Appl. Math., 76 (2016), pp. 411-432] developed the notion of complex balancing for stochastic systems. We define and establish the relations between reaction balanced measure, complex balanced measure, reaction vector balanced measure, and cycle balanced measure and prove that with mild additional hypotheses, the former two are stationary distributions. Furthermore, in the spirit of an earlier work by Joshi [Discrete Contin. Dyn. Syst. Ser. B, 20 (2015), pp. 1077-1105] we give sufficient conditions under which detailed balance of the stationary distribution of Markov chain models implies the existence of positive detailed balance equilibria for the related deterministic reaction network model. Finally, we provide a complete map of the implications between balancing properties of deterministic and corresponding stochastic reaction systems, such as complex balance, reaction balance, reaction vector balance, and cycle balance

Holotype CES 091037, female, from Periyar, Kerala, India, 9 ° 58402 N 77 ° 34902 E, leg. J. Joshi, ix. 2009. Paratype CES 091038, female, from type locality, same collection details. Etymology. For the Periyar region. Diagnosis. Cephalic plate slightly longer than wide. Basal three antennal articles glabrous dorsally. Forcipular tooth plates longer than wide. Paramedian sutures nearly complete on most sternites. All legs lacking tarsal, tibial and femoral spurs. Femur of ultimate leg with pair of longitudinal grooves on dorsal surface, the more medial of them contiguous with a longitudinal groove on the prefemur and tibia; tarsus of ultimate legs markedly more slender than short, robust tibia and femur. Coxopleural process short; pores relatively sparse. Description. Length to 58 mm. 17 antennal articles; basal three articles glabrous dorsally, two glabrous ventrally. Anterior longitudinal median furrow at most ca 20 % length of cephalic plate, considerably shorter in holotype (Fig. 57). Cephalic plate and T 1 orange; anterior tergites mixed blue and yellow-brown; tergites in posterior half of trunk mostly light brown with blue margins; antennae and legs 1–20 pale yellow apart from pale blue tarsi on leg 20. Forcipular coxosternal tooth plates longer than wide, markedly so in holotype (Figs 58, 59); four main teeth, not arranged in groups, the outer tooth smaller than the inner three; base of tooth plates defined by relative acute oblique sutures diverging at 105 °– 125 °. Trochanteroprefemoral process with indistinctly defined teeth along inner margin. Second maxillary claw with slender accessory spurs. Article 2 of telopodite bearing a slender spine distally. Tergites with paramedian sutures complete from TT 4 or 5, short suture confined to anterior edge of TT 2–3. Tergites marginate from 5 or 6. Tergites smooth, lacking median ridge or keels (Fig. 66) apart from weak, incomplete median keel on tergite of ultimate leg-bearing segment; lateral part of posterior tergites with low, irregularly anastomosing ridges. Sternites with paramedian sutures nearly complete in most segments, especially in anterior part of trunk, those in posterior few segments ca 80 % length of sternite. Tergite of ultimate leg-bearing segment with lateral margins gently converging posteriorly, posterolateral margins mostly straight, converging to a broad, evenly rounded posteromedial margin (Fig. 61). Sternite of ultimate leg-bearing segment with sides converging posteriorly, posterior margin gently concave (Fig. 62). Coxopleural process short, barely inflected from posterolateral margin of coxopleuron in ventral view (Fig. 62), with two apical spines, lacking lateral spine(s). Pore field terminating strongly beneath dorsal margin of coxopleuron (Fig. 60); pores relative sparse; non-porose area on coxopleural process short. Ultimate leg prefemur with width at distal end nearly 40 % its length, of nearly equal width along its length (Fig. 64). Prefemoral spines robust, with a short, curved apex (Fig. 63): VL 3, VM 2 (3), DM 2. Femur with width at its distal end 40–50 % its length (Fig. 64). Dorsal, medial and lateral surfaces of prefemur and femur rugose, with large, shallow pits; similar pits adjacent to longitudinal groove on dorsomedial side of tibia (Fig. 65). Ultimate leg tarsus 1 2.5 times length of tarsus 2; tarsus 1 2–3.3 times longer than pretarsus; pretarsus with pair of short accessory claws. Discussion. This species is the most morphologically distinct among Indian Digitipes, readily identified by its complete absence of tarsal spurs, the long paramedian sutures on the sternites (nearly complete versus not more than 35 % the length of the sternites in other Indian Digitipes), and by the robust, dorsally-grooved prefemur, femur and tibia of the ultimate legs. Complete paramedian sutures on the sternites are known elsewhere in Digitipes in the type species, D. verdascens Attems. The two known specimens are both females so no data are at hand with respect to the condition of the femoral process in males. Despite its distinctive character states, its membership in Digitipes is indicated by the support at the nodes in the phylogeny that unite it with Group A of Joshi and Karanth (2012) (posterior probability 0.94 for it grouping with D. coonoorensis and D. indicus) and that clade as a whole grouping with Groups B and C (posterior probability 1, bootstrap support 100 %).Published as part of Joshi, Jahnavi & Edgecombe, Gregory D., 2013, Revision of the scolopendrid centipede Digitipes Attems, 1930, from India (Chilopoda: Scolopendromorpha): reconciling molecular and morphological estimates of species diversity, pp. 99-145 in Zootaxa 3626 (1) on page 116, DOI: 10.11646/zootaxa.3626.1.5, http://zenodo.org/record/21862
Magnetic resonance imaging procedure for pelvic fracture urethral injuries and recto urethral fistulas: A simplified protocol
No full textObjective: The urethral gap in pelvic fracture urethral injury (PFUI) is traditionally assessed using voiding cystourethrogram (VCUG) and retrograde urethrogram (RGU). Magnetic resonance imaging (MRI) is performed in complex cases. We assessed the refined “Joshi” MRI protocol to evaluate complex urethral defects after PFUI. Material and methods: A prospective study was conducted at our center from January 2018 to January 2020, involving patients aged >18 years with PFUI, suitable for MRI, and those who gave consent to perform standard RGU, VCUG, and MRI using standard and “Joshi” protocol. Forty men were included in the study. Distance between urethral/prostatic stumps was measured. Image quality was scored by four radiologists and four urologists. The surgical approach and type of PFUI repair were noted. We also established the need for inferior pubectomy by assessing the position of the posterior urethra (membranous) in relation to a horizontal line drawn from the lower edge of the pubic bone anteriorly to the rectum posteriorly in a sagittal image. Results: The mean age was 30 years (SD, 5.25; range, 21–43), and the time from injury to imaging was 4 months (3–10 months); 40% of the men underwent crural separation, 57.5%, inferior pubectomy, and 2.5%, crural rerouting. There was a difference of 0.3 to 1.1 cm in the urethral gap measurements between MR images using the standard versus “Joshi” technique. MRI identified complex injuries such as rectourethral fistula, the need for inferior pubectomy, and the orientation of the posterior urethra. Urologists’ and radiologists’ satisfaction scores for the MR images were satisfactory to excellent. If the posterior urethra was over the defined mark, there was a 100% likelihood of inferior pubectomy (23/40 patients). Conclusion: MR image acquisition using the “Joshi” protocol provided high-quality anatomical informa-tion in PFUI cases to assist with surgical planning.Full Tex
How to do a penile urethroplasty using a novel self‐retaining penile retractor
No full textEffective retraction and clear exposure of urethral tissue is essential in reconstructive penile surgery. The Joshi–Kulkarni retractor provides stable, bloodless operative exposure via non-traumatic tissue compression at the base of penis. The self-retaining design of this retractor also improves ergonomics thereby reducing surgeon fatigue. In this article, we describe how to do a penile urethroplasty by using the Joshi–Kulkarni penile retractor.No Full Tex

Herbal drugs and fingerprints : evidence based herbal drugs / Devi Datt Joshi.
No full textIncludes bibliographical references and index.xvi, 252 pages :Evidence based herbal drugs are on hi-acceptance day by day due to health friendly nature compared to synthetic drugs. The active ingredients in herbal drugs are different chemical classes, e.g. alkaloids, coumarins, flavonoids, glycosides, phenols, steroids, terpenes etc., are identified at molecular level using current analytical practices, which are unique characteristic, as finger, so known as fingerprints. The fingerprints are used for assessment of quality consistency and stability by visible observation and comparison of the standardized fingerprint pattern, have scientific potential to decipher the claims made on these drugs for authenticity and reliability of chemical constituents, with total traceability, which starts from the proper identification, season and area of collection, storage, their processing, stability during processing, and rationalizing the combinational in case of polyherbal drugs. These quality oriented documents have ample scientific logics so well accepted globally by regulatory authorities and industries, to determine intentional/ unintentional contamination, adulteration, pollutants, stability, quality, etc. parameters. Based on geo-climatic factors, a same plant species has different pharmacological properties due to different ingredients; such regional and morphological variations are identified by fingerprints, at the time of collection of the medicinal herb. The chromatographic (TLC, HPTLC, HPLC, GC,) and spectral (UV-Vis., FTIR, MNR, MS, LC-MS, GC-MS etc.) techniques have world-wide strong scientific approval as validated methods to generate the fingerprints of different chemical classes of active ingredients of herbal drugs. Presently there is a need for a book having all the fingerprinting techniques for herbal drugs at a place with theory, case studies and art to discover patentable forms. The present book is a mile stone in the subject, to be utilized by Scientists, Medical Doctors, Technicians, Industrialists, Researchers, and Students both in PG and UG level
