We report a case of a young male pati.nt sufferi.g from congeni.al Anti.Thrombi. i.i.(AT i.i. defi.i.ncy, presented wi.h four major thromboti. events. These events were acute coronary syndrome (Non-ST elevati.n myocardi.l i.farcti.n), cerebral i.farcti.n, peri.heral acute upper li.b (UL) i.chemi. and bi.ateral extensi.e deep venous thrombosi.. The latter two developed despi.e that the pati.nt was recei.i.g full anti.oagulati.n therapy. Hi. i.ternati.nal normali.ed rati. (i.R) was 2.5. Eventually, the pati.nt developed pulmonary emboli.m and di.d. He had a promi.ent fami.y hi.tory of thromboti. events.

Hi.hly effi.i.nt si.ver hali.e nanoparti.les (AgX, X = Cl, Br NP’s) were successfully synthesi.ed by faci.e and template-free di.ect-preci.i.ati.n method usi.g potassi.m chlori.e, potassi.m bromi.e and si.ver ni.rate as reacti.e sources. The as-prepared AgX NP’s were characteri.ed by FTi., thermogravi.etri. analysi., XRD, EDX and HRTEM. The anti.i.robi.l suscepti.i.i.i.s agai.st two Gram-posi.i.e bacteri. (Baci.lus cereus, Staphylococcus aureus) and four Gram-negati.e bacteri. (Salmonella typhi. Escheri.hi. coli.

The anti.acteri.l and anti.ungal results suggest that the prepared AgX NP’s show hi.h acti.i.y agai.st the tested organi.ms compared to tetracycli.e and Nystati. taken as standard drugs. As an appli.ati.n, the use of the prepared AgX NP’s as photo catalyst for the decontami.ati.n of malathi.n as VX chemi.al warfare agent (CWA) sti.ulant from water sample was extensi.ely studi.d.

However, the i.e extent had decreased by 0.432 ***^(2) compared wi.h 2022.

Si.pler formulas are deri.ed for one-range addi.i.n theorems for the i.teger and noni.teger n generali.ed ex- ponenti.l type orbi.als, momentum space orbi.als, and hyperspheri.al harmoni.s wi.h hyperboli. cosi.e （GETO HC, GMSO HC, and GHSH HC） i. posi.i.n, momentum and four-di.ensi.nal spaces, respecti.ely. The fi.al results are expressed i. terms of one-range addi.i.n theorems of complete orthonormal sets of Ca-exponenti.l type orbi.als, Ca- momentum space orbi.als and za-hyperspheri.al harmoni.s. We noti.e that the one-range addi.i.n theorems for i.teger and noni.teger n-Slater type orbi.als and Gaussi.n type orbi.als i. posi.i.n, momentum and four di.ensi.nal spaces are speci.l cases of GETO HC, GMSO HC, and GHSH HC. The theorems presented can be useful i. the accurate study of the electroni. structure of atomi. and molecular systems.
