Backgroun.: Mitochon.rial cytopathies (MCs) are a heterogen.ous group of clin. cal en.ities, some of which have classic phen.types. Magn.tic reson.n.e imagin. (MRI) has been.reported to be helpful in.the diagn.sis of MC. Obj.ctive: To corr elate the most common.brain.MRI fin.in.s reported in.patien.s with MC with the c lin.cal fin.in.s in.patien.s in.differen. MC subgroups. Design. Case series. Set tin.: Patien.s with MCs seen.at the In.tituto n.tion.l de Cien.ias Médicas y n. tritin.Salvador Zubirn. Mexico City, Mexico. Patien.s: Twen.y-on. patien.s with MC with the followin. phen.types: chron.c progressive extern.l ophthalmople gia (n.7), Kearn.-Sayre syn.rome (n.7), mitochon.rial n.urogastroin.estin.l en. ephalopathy (n.6), an. myoclon.c epilepsy with ragged red fiber myopathy (n.1). Results: Brain.MRI abn.rmalities were foun. in.20 (95%) of 21 patien.s. The mos t frequen. abn.rmalities were widespread white matter hyperin.en.ity in.19 patie n.s (90%), supraten.orial cortical atrophy in.18 patien.s (86%), an. cerebella r atrophy in.13 patien.s (62%). Widespread white matter hyperin.ten.ity (P n. supraten.orial cortical atrophy (P=.001) were each corr elated sign.fican.ly with MC. Subsequen. subgroup an.lyses showed that the absen.ce of basal gan.lia hyperin.en.ity was correlated with Kearn.-Sayre syn.rome (P n. the presen.e of supraten.orial cortical atrophy was correlated with mitochon.rial n.urogastroin.estin.l en.ephalopathy (P=.005). Con.lusion.: The p resen.e of widespread white matter hyperin.en.ity an./or supraten.orial cortical atrophy in.brain.MRI may help to establish the diagn.sis of MC. The radiologist has a role to play in.the workup of MC by con.irmin. the diagn.sis an. possibly distin.uishin. differen. subgroups of MC.

An.ba rosaeodora essen.ial oil (RO) has been.tradition.lly used in.n.tural medicin. as a substitute for an.ibiotics due to its n.table an.idepressan. an. an.ibacterial properties. Salmon.lla, a prevalen. pathogen.in.foodborn. illn.sses, presen.s a maj.r challen.e to curren. an.ibiotic treatmen.s. However, the an.ibacterial efficacy an. mechan.sms of action.of RO again.t Salmon.lla spp. remain.un.erexplored. This study aims to elucidate the chemical composition.of RO, evaluate its an.ibacterial activity an. mechan.sms again.t Salmon.lla in.vitro, an. further delin.ate its an.i-in.lammatory mechan.sms in.vivo durin. Salmon.lla in.ection. Gas chromatography-mass spectrometry (GC-MS) was utilized to characterize the chemical con.tituen.s of RO. The an.ibacterial activity of RO was assessed usin. min.mal in.ibitory con.en.ration.(MIC) an. time-kill assays. Various biochemical assays were employed to un.over the poten.ial bactericidal mechan.sms. Addition.lly, mouse an. chick models of Salmon.lla in.ection.were established to in.estigate the prophylactic effects of RO treatmen.. RO exhibited sign.fican. an.ibacterial activity again.t both Gram-positive an. Gram-n.gative bacteria, with an.MIC of 4 mg·mL−1 for Salmon.lla spp. RO treatmen. resulted in.bacterial damage through the disruption.of lipid an. purin. metabolism. Moreover, RO reduced in.0}ry an. microbial colon.zation.in.in.ected mice an. chicks. RO treatmen. also modulated the host in.lammatory respon.e by in.ibitin. proin.lammatory pathways.

This research en.ails the study of heat an. mass tran.fer of n.n.fluid flow in.a fluidized bed dryer used in.tea dryin. processes in.presen.e of in.uced magn.tic field. A mathematical model describin. the fluid flow in.a Fluidized bed dryer was developed usin. the n.n.in.ar partial differen.ial equation.. Due to their n.n.lin.arity, the equation. were solved n.merically by use of the fin.te differen.e method. The effects of physical flow parameters on.velocity, temperature, con.en.ration.an. magn.tic in.uction.profiles were studied an. results were presen.ed graphically. From the mathematical an.lysis, it was deduced that addition.of silver n.n.particles in.o the fluid flow en.an.ed velocity an. temperature profiles. This led to improved heat tran.fer in.the fluidized bed dryer, hen.e amplifyin. the tea dryin. process. Furthermore, it was n.ted that in.uced magn.tic field ten.s to decrease the fluid velocity, which results in.un.form distribution.of heat leadin. to efficien. heat tran.fer between.the tea particles an. the fluid, thus improvin. the dryin. process. The research fin.in.s provide in.ormation.to in.ustries on.ways to optimize thermal performan.e of fluidized bed dryers.

A Study of the TPS Based Beam-Matchin. Con.ept for Medical Lin.ar Accelerators at a Tertiary Hospital

引用

In.ern.tion.l j.urn.l of Medical Physics, Clin.cal en.in.erin. an. Radiation.On.ology 2024年第1期13卷 16-25页

作者： n.ombela n. Lethukuthula Rovetto j. n.colas n.thwadzi C. Luten.o Mpumelelo n.athi Departmen. of Radiation.On.ology Steve Biko Academic Hospital Pretoria South Africa Departmen. of Medical Physics University of Pretoria Pretoria South Africa Departmen. of Medical Physics Sefako Makgatho Health Sciences University Ga-Rankuwa South Africa

The flexibility in.radiotherapy can.be improved if patien.s can.be moved between.an. on. of the departmen.’s medical lin.ar accelerators (LIn.Cs) without the n.ed to chan.e an.thin. in.the patien.’s treatmen. plan. For this to be possible, the dosimetric characteristics of the various accelerators must be the same, or n.arly the same. The purpose of this work is to describe further an. compare measuremen.s an. parameters after the in.tial ven.or-recommen.ed beam matchin. of the five LIn.Cs. Deviation. related to dose calculation. an. to beam matched accelerators may compromise treatmen. accuracy. The safest an. most practical way to en.ure that all accelerators are within.clin.cal acceptable accuracy is to in.lude TPS calculation. in.the LIn.Cs matchin. evaluation. Treatmen. plan.in. system (TPS) was used to create three photon. plan. with differen. field sizes 3 × 3 cm, 10 × 10 cm an. 25 × 25 cm at a depth of 4.5 cm in.Perspex. Calculated TPS plan. were sen. to Mosaiq to be delivered by five LIn.Cs. TPS plan. were compared with five LIn.Cs measuremen.s data usin. Gamma an.lyses of 2% an. 2 mm. The results suggest that for four out of the five LIn.Cs, there was gen.rally good agreemen., less than.a 2% deviation.between.the plan.ed dose distribution.an. the measured dose distribution. However, on. specific LIn.C n.med “Asterix” exhibited a deviation.of 2.121% from the plan.ed dose. The results show that all of the LIn.Cs’ performan.e were within.the acceptable deviation.an. deliverin. radiation.dose con.isten.ly an. accurately.
