A basement show is a musical performance, often of the punk rock or hardcore punk variety, that is held in the basement of a residential home, rather than at a traditional venue.
 These are also sometimes referred to as "house shows" as they can happen anywhere in a residential house, not just in the basement.
 Basement shows are normally held for a variety of reasons, including:
Thin basement membrane disease (TBMD, also known as "benign familial hematuria" and "thin basement membrane nephropathy") is, along with IgA nephropathy, the most common cause of asymptomatic hematuria.
 The only abnormal finding in this disease is a thinning of the basement membrane of the glomeruli in the kidneys.
 Its importance lies in the fact that it has a benign prognosis, with patients maintaining a normal kidney function throughout their lives.
In the Basement ("Im Keller") is a 2014 Austrian documentary film directed by Ulrich Seidl about people and their obsessions, and what they do in their basements in their free time.
 It was part of the Out of Competition section at the 71st Venice International Film Festival.
A basement apartment is an apartment located below street level, underneath another structure—usually an apartment building, but possibly a house or a business.
 Rent in basement apartments is usually much lower than it is in above-ground units, due to a number of deficiencies common to basement apartments.
 The apartments are usually cramped, and tend to be noisy, both from uninsulated building noises and from traffic on the adjacent street.
 They are also particularly vulnerable to burglary, especially those with windows at sidewalk level.
 In some instances, residential use of below-ground space is illegal, but is done anyway in order for the building owner to generate extra income.
Feiyu Show () is a 2014 Chinese documentary film directed by Sun Hong.
 It was released in China on October 23, 2014.
Thick-skinned deformation is a geological term which refers to crustal shortening that involves basement rocks and deep-seated faults as opposed to only the upper units of cover rocks above the basement which is known as thin-skinned deformation.
 While thin-skinned deformation is common in many different localities, thick-skinned deformation requires much more strain to occur and is a rarer type of deformation.
Diffuse proliferative nephritis (DPN) or glomerulonephritis (DPGN) is a type of glomerulonephritis that is the most serious form of renal lesions in SLE and is also the most common, occurring in 35% to 60% of patients.
 Most of the glomeruli show endothelial and mesangial proliferation affecting the entire glomerulus, leading to diffuse hypercellularity of the glomeruli, producing in some cases epithelial crescents that fill Bowman's space.
 When extensive, immune complexes create an overall thickening of the capillary wall, resembling rigid "wire loops" on routine light microscopy.
 Electron microscopy reveals electron-dense subendothelial immune complexes (between endothelium and basement membrane).
 Immune complexes can be visualized by staining with fluorescent antibodies directed against immunoglobulins or complement, resulting in a granular fluorescent staining pattern.
 In due course, glomerular injury gives rise to scarring (glomerulosclerosis).
 Most of these patients have hematuria with moderate to severe proteinuria, hypertension, and renal insufficiency.
The dermoepidermal junction is the area of tissue that joins the epidermal and the dermal layers of the skin.
 The basal cells in the stratum basale of the epidermis connect to the basement membrane by the anchoring filaments of hemidesmosomes; the cells of the papillary layer of the dermis are attached to the basement membrane by anchoring fibrils, which consist of type VII collagen.
A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane.
 Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.
 Although this epithelium is referred to as squamous, many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface.
 In the deeper layers, the cells may be columnar or cuboidal.
 There are no intercellular spaces.
 This type of epithelium is well suited to areas in the body subject to constant abrasion, as it is the thickest and layers can be sequentially sloughed off and replaced before the basement membrane is exposed.
 It forms the outermost layer of the skin and the inner lining of the mouth, esophagus and vagina.
A Pittsburgh toilet, often called a "Pittsburgh potty", is a common fixture in pre-World War II houses built in Pittsburgh, Pennsylvania, United States.
 It consists of an ordinary flush toilet installed in the basement, with no surrounding walls.
 As Pittsburgh was historically an industrial town, still called "The Steel City," toilets such as these could be used by steelworkers and miners: grimy from the day's labor, they could use an exterior door to enter the basement directly from outside and use the basement's shower and toilet before heading upstairs.
 Most of these toilets are paired with a crude basement shower apparatus and large sink, which often doubles as a laundry basin.
 Also, because western Pennsylvania is a steep topographical zone, many basements have their own entryway, allowing homeowners to enter from their yard or garage, cleanse themselves promptly in their basement, and then ascend their basement stairs refreshed.
